PART I

Item 1. BUSINESS

Labcorp® (Labcorp or the Company) is a global leader of innovative and comprehensive laboratory services that provides vital information to help doctors, hospitals, pharmaceutical companies, researchers, and patients make clear and confident decisions. By leveraging its unparalleled diagnostics and drug development capabilities, the Company provides insights and accelerates innovations to improve health and improve lives. With more than 67,000 employees, the Company serves clients in more than 100 countries.

The Company is organized under two segments, consisting of Diagnostics Laboratories (Dx), which includes routine testing and specialty/esoteric testing, and Biopharma Laboratory Services (BLS), consisting of Early Development Research Laboratories and Central Laboratory Services. The Company's strength in science, technology, and innovation, as well as its global scale, enable it to play a leading role in advancing healthcare across the globe. The Company worked on 90% of the new drugs approved by the FDA in 2023 and performed more than 600 million tests for patients around the world.

The significant reach, breadth, and advancement of the Company's offerings have resulted in Base Business revenue growth of 11.8% from 2022 through 2023 and 7.2% versus 2019 CAGR. Base Business includes the Company's business operations except for COVID-19 PCR and antibody testing (COVID-19 Testing).

For the period ended December 31, 2023, the Company generated revenues of $12,161.6 million, diluted earnings per share from continuing operations of $4.33, and had a total operating cash flow from continuing operations of 1,202.3 million.

The Company believes that science, technology, and innovation drive its continued success, differentiate the Company, and are foundational to its future. They are critical to the Company's ability to carry out its mission to improve health and improve lives.

Spin-off of Fortrea Holdings Inc.

On June 30, 2023, the Company completed the previously announced separation (spin-off) of its former clinical development and commercialization services (CDCS) business, Fortrea Holdings Inc. (Fortrea).

The spin-off of Fortrea was achieved through the Company’s pro-rata distribution of 100% of the outstanding shares of Fortrea common stock to holders of record of Labcorp common stock (Common Stock). Each holder of record of Common Stock received one share of Fortrea common stock for every share of Common Stock held at 5:00 p.m., Burlington, North Carolina time on June 20, 2023, the record date for the distribution.

In June 2023, Fortrea, prior to the spin-off and while a subsidiary of the Company, issued $570.0 million of 7.500% senior secured notes due 2030 (the Fortrea Notes). The proceeds from the Fortrea Notes were used to fund cash payments of approximately $1,600.0 million to the Company in connection with the spin-off. The Company does not guarantee the Fortrea Notes following the spin-off. Also in June 2023, Fortrea entered into three floating secured overnight financing rate (SOFR) credit facilities totaling $1,520.0 million. These are comprised of $450.0 million Revolver maturing June 30, 2028; $500.0 million Term Loan A maturing June 30, 2028; and $570.0 million Term Loan B maturing June 30, 2030.

Upon closing of the spin-off, Fortrea made a cash distribution to the Company of approximately $1,600.0 million as partial consideration for the assets that the Company contributed to Fortrea in connection with the spin-off. The Company used these proceeds to repurchase approximately $1,000.0 million in the aggregate of Common Stock pursuant to accelerated share repurchase agreements and paying down $300.0 million of debt that matured in 2023, with the remaining funds to be returned to shareholders through additional future share repurchases and/or cash dividends.

All current and historical operating results of Fortrea are presented as Discontinued Operations, net of tax, in the consolidated statement of operations. The spin-off is expected to be treated as a tax-free transaction for the Company and its shareholders for U.S. federal income tax purposes.

As a result of the spin-off, the Company recast its segment results to exclude the historical results of the CDCS business for all periods presented. The remaining operations of the previously reported Drug Development segment has been renamed the Biopharma Laboratory Services segment.

The spin-off provides the Company with:

•strengthened strategic flexibility and operational focus to pursue specific market opportunities and better meet customer needs;

•focused capital structures and capital allocation strategies to drive innovation and growth;

•a more targeted investment opportunity for different investor bases; and

•the ability to align its particular incentive compensation with its financial performance.

Index

Following the spin-off, the Company believes that it is positioned to:

•invest in R&D and innovation to develop and launch diagnostic advancements globally in key clinical areas including oncology, women's health, autoimmune disease and neurology through organic and inorganic opportunities;

•utilize its worldwide laboratory network to serve a broad, growing and global customer base including pharmaceutical and biotechnology companies, physicians, health systems, consumers, and other start-ups and laboratories that require lab services or diagnostic testing; and

•launch innovative tests globally, providing patients, physicians, health systems and pharmaceutical companies with access to its advanced science, technology and diagnostic capabilities.

Enterprise Strategy

Through leadership in science, technology and innovation, the Company provides vital information and services to help its customers make clear and confident health decisions and helps millions of people improve health and improve lives.

The Company is expanding its role in the rapidly evolving healthcare market by strengthening its positions across its portfolio of capabilities, growing strategic opportunities that drive new business, and differentiating its unique offerings, capabilities, and financial performance. The Company is focused on two near-term strategic opportunities for growth across both Dx and BLS:

1.To Be the Partner of Choice for Health Systems and Local and Regional Laboratories

The Company expects industry consolidation to continue, as hospitals and health systems focus on investing in core patient care services. The depth and the breadth of opportunity and the quality of the pipeline is robust, and the Company is optimistic about continued expansion. The Company seeks partnerships that meet financial criteria, including being accretive in the first year, returning each transaction's cost of capital within three years, and providing a clear path to improve margins.

The Company signed or completed six collaboration transactions with health systems in 2023. The Company believes it is an attractive partner for hospitals and health systems for multiple reasons:

•Innovative product offerings in high growth specialty areas: Many hospital and health systems want to be at the forefront of their offerings to patients with the latest specialty testing;

•Industry-leading test portfolio and national presence: Hospitals and health systems seek a partner who can scale as they expand and grow;

2. To Lead in the Development, Licensing, and Scaling of Specialty Testing Including Companion Diagnostics

The Company is focused on four primary specialty testing areas: oncology, women's health, autoimmune disease, and neurology, which the Company believes represent significant growth areas. The development of specialty tests and companion diagnostics are attractive to health systems partners and biopharma as they continue to develop more products in specialty areas and cell and gene therapy. The Company has demonstrated its ability to provide comprehensive portfolios in these four areas, which comprise more than half of clinical trials conducted in its Central Laboratory Services business.

Longer-term, the Company is focused on three enterprise-wide strategic priorities to drive growth:

1.Establish leadership and partnership capabilities in cell and gene therapy

Cell and gene therapy is a growing focus of biopharma pipelines, with more than 2,000 clinical trials being conducted globally and representing approximately 20% of all biopharma drug pipelines. The Company expects the cell and gene therapy market to grow at a substantially higher rate than other types of therapies over the next five years. As cell and gene therapies expand, the Company has an opportunity to leverage its strong drug development capabilities, scientific expertise, and pharma relationships to become a development lab of choice. Longer-term as these therapies develop, the Company believes it can harness its diagnostic assets to support biopharma in commercializing cell and gene therapies and scaling these therapies through its hospital and health system business over time.

2. Expand consumer-centric capabilities

Consumerism trends, such as greater choice, convenience, and transparency, continue to have a growing influence across the healthcare landscape and present new opportunities for growth. Through its core customer groups, the Company has more than 150 million customer interactions per year and has invested in modern capabilities to digitize and improve the patient journey across patient service centers. Through the Labcorp OnDemand channel, the Company has also demonstrated its ability to connect with consumers directly and is now offering more than 50 health and wellness tests through Labcorp OnDemand. Across its core businesses, the Company has an opportunity to make strategic investments to continue to enhance the customer experience through its patient portal, patient service center network, and other consumer-focused initiatives, and to capitalize on select direct revenue streams that require elevated consumer capabilities. The Company’s scaled operations, trusted brand, scientific leadership, and broad customer base are key differentiators that will support its efforts to expand over time to meet the evolving needs of its customer groups.

3. Expand global reach, including through companion diagnostics

International expansion of specialized diagnostics remains a key opportunity for future growth as the Company continues to add to its pipeline of specialty diagnostics. The Company is already a key partner to biopharma in companion diagnostics (CDx) with greater than $500.0 million in net orders in the BLS segment in 2023. As its pipeline of specialty diagnostics grows, the Company will seek to leverage its scientific leadership in new markets through a differentiated set of capabilities:

•A global central laboratory footprint

•Innovative science and technology

•A comprehensive and competitive testing portfolio

•Deep customer relationships in diagnostics and biopharma laboratory services

As CDx continue to become more important for serving customers across the enterprise, the Company has a unique set of capabilities to be an end-to-end partner to biopharma and will continue to expand these capabilities to fuel further targeted growth internationally.

COVID-19 Pandemic Response

The Company has supported the global response to COVID-19 since the earliest stages of the pandemic, and it continues to contribute to ongoing efforts.

The Company's additional contributions to the pandemic response in 2023 included assisting in the identification and monitoring of COVID-19 variants and surges in confirmed cases. The Company maintained its ability to quickly scale up COVID-19 PCR testing capacity throughout the year, even during periods of reduced demand. In doing so, the Company was able to immediately and effectively respond to surges in positive cases and testing needs. The Company performed approximately 13 million COVID-19 PCR tests and 1 million antibody tests in 2023, and since the start of the pandemic has performed approximately 74 million COVID-19 PCR tests and 9 million antibody tests.

Capital Allocation

The Company believes it has a strong track record of deploying capital to investments that enhance the Company's business and return capital to shareholders.

During 2023, the Company invested $671.5 million in strategic business acquisitions. The acquisitions have enhanced the Company’s service offerings, expanded its customer and revenue mix, and strengthened and broadened the scope of its geographic presence. The Company continues to evaluate acquisition opportunities that leverage the Company’s core competencies, complement existing scientific and technological capabilities, increase the Company’s presence in key geographic, therapeutic and strategic areas, and meet or exceed the Company’s financial criteria.

During 2023, the Company repurchased 4.8 million shares of Common Stock at an average price of $206.85 per share for a total cost of $1,000.0 million. The Company has accrued $9.0 million of excise tax related to this accelerated share repurchase, which will be paid in April 2024. At the end of 2023, the Company had outstanding authorization from the Board to purchase $530.4 million of Common Stock.

During 2023, capital expenditures were $453.6 million. The Company expects capital expenditures in 2024 to be approximately 3.5% of revenues, primarily in connection with projects to support growth in the Company's core businesses, facility expansion and updates, projects related to its LaunchPad initiative, and further acquisition integration initiatives.

The Company will continue to evaluate opportunities for strategic deployment of capital in light of market conditions.

Seasonality and External Factors

The Company experiences seasonality across its business. For example, testing volume generally declines during the year-end holiday period and other major holidays and can also decline due to inclement weather or natural disasters. Testing volumes can also be impacted by changes in the global economy, exchange rate fluctuations, political and regulatory changes, the progress of ongoing studies and the startup of new studies, as well as the level of expenditures made by the pharmaceutical, biotechnology and medical device industries in R&D. Declines in testing volume reduce revenues, operating margins and cash flows.

In 2023, approximately 12.9% of the Company's revenues were billed in currencies other than the U.S. dollar, with the Swiss franc, British pound, Canadian dollar, and the euro representing the largest components of its currency exposure.

Given the seasonality and changing economic factors impacting the business, comparison of the results for successive quarters may not accurately reflect trends or results for the full year.

The Company's Business

For the year ended December 31, 2023, the Company's revenues from continuing operations were $12.2 billion, an increase of 2.5% from $11.9 billion in 2022. The 2.5% increase in revenues for the year ended December 31, 2023, as compared to the corresponding period in 2022 was due to acquisitions, net of divestitures of 1.7%, organic revenue of 0.6%, and favorable foreign currency translation of 0.2%. The 0.6% increase in organic revenue was due to an 8.7% increase in the Company's organic Base Business, partially offset by an 8.1% decrease in COVID-19 Testing.

The Company reports its business in two segments, Dx and BLS. In 2023, Dx and BLS contributed 77% and 23%, respectively, of revenues to the Company, and in 2022 contributed 77% and 23%, respectively. Nearly all of Dx’s revenues are generated in the U.S., with a smaller portion in Canada and a relatively small amount in the rest of the world. BLS’s revenues are nearly evenly split between the U.S. and the rest of the world, with approximately 42% derived from the U.S. and approximately 58% from other countries. Although this allocation of revenues provides some protection from economic shifts in any one country, it is still heavily tilted towards the U.S. As a result, the Company continues to actively explore new business opportunities outside the U.S. to further diversify its sources of revenues. The Company's revenues by segment payers/customer groups and by geography for the years ended December 31, 2023, 2022 and 2021 are as follows:

Dx is an independent clinical laboratory business. It offers a comprehensive menu of frequently requested core testing and specialty testing through an integrated network of primary and specialty laboratories across the U.S. and Canada. This network is supported by a sophisticated information technology system, with more than 80,000 electronic interfaces to deliver test results, nimble and efficient logistics, and local labs offering rapid response testing.

Dx also provides patient access points that are strategically and conveniently located throughout the U.S., including more than 2,000 patient service centers (PSCs) and more than 6,000 in-office phlebotomists located in customer offices and facilities. Although testing for healthcare purposes and customers who provide healthcare services represents the most significant portion of the clinical laboratory industry, clinical laboratories also perform testing for other purposes and customers, including employment and occupational testing, DNA testing to determine parentage and to assist in immigration eligibility determinations, environmental testing, wellness testing, toxicology testing, pain management testing, and medical drug monitoring. Dx offers an expansive test menu that includes a wide range of clinical, anatomic pathology, genetic and genomic tests, and regularly adds new tests and improves the methodology of existing tests to enhance patient care. Dx also offers more than 50 consumer-initiated wellness testing available online through its Labcorp OnDemand™ platform. Dx has more than 160 million patient interactions per year, including patients getting lab results, going to the Company's websites, and purchasing testing online through Labcorp OnDemand.

As part of an ongoing commitment to be an efficient and high-value provider of laboratory services, Dx implemented and has maintained a comprehensive business process improvement initiative known as LaunchPad. The initiative was designed to reengineer the Company's systems and processes to create a sustainable and more efficient business model, and to improve the experience of all stakeholders.

Effect of U.S. Market Changes on the Clinical Laboratory Business

The delivery of, and reimbursement for, healthcare continues to change in the U.S., impacting all stakeholders, including the clinical laboratory business. Medicare (which principally serves patients who are 65 and older), Medicaid (which principally serves low-income patients) and insurers have increased their efforts to control the cost, utilization and delivery of healthcare services. Measures to regulate healthcare delivery in general and clinical laboratories in particular have resulted in reduced prices, added costs, increased coverage denials and claims edits, and decreased test utilization for the clinical laboratory industry by imposing new, increasingly complex regulatory and administrative requirements. The government also has continued to adjust the Medicare and Medicaid fee schedules at the national and local level, and the Company believes that pressure to reduce government reimbursement will continue.

Fees for most laboratory services reimbursed by Medicare are established in the Clinical Laboratory Fee Schedule (CLFS) and fees for other testing reimbursed by Medicare, primarily related to pathology, are covered by the Physician Fee Schedule (PFS). During 2023, approximately 8.8% of Dx’s revenue was reimbursed under the CLFS (8.9% in 2022), and approximately 0.4% was reimbursed under the PFS (0.4% in 2022). Dx has experienced governmental reimbursement reductions as a direct result of several Congressional acts and regulatory initiatives, including those designed to control healthcare expenses reimbursed by government programs through a combination of reductions to fee schedules, incentives to physicians to participate in alternative payment models such as risk-sharing, and new methods to establish and adjust fees.

Index

The most significant of these developments was the Protecting Access to Medicare Act (PAMA), which became law on April 1, 2014, and which went into effect on January 1, 2018. Beginning in 2018, under PAMA, the Centers for Medicare and Medicaid Services (CMS) of the U.S. Department of Health and Human Services (HHS) set the CLFS using the weighted median of reported private payer prices paid to certain laboratories that receive a majority of their Medicare revenue from the CLFS and PFS and that bill Medicare under their own National Provider Identifier (NPI). Applicable labs, including Dx, were required to begin reporting their test-specific private payer payment amounts to CMS during the first quarter of 2017. CMS used that private market data to calculate weighted median prices for each test (based on applicable current procedural technology (CPT) codes) to represent the new CLFS rates beginning in 2018, subject to certain phase-in limits. For 2018 through 2020, a test price could not be reduced by more than 10.0% per year. PAMA resulted in a net reduction in reimbursement revenue of approximately $245.0 million between 2018-2020 from all payers affected by the CLFS.

Due to enactment of the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) passed by Congress on March 27, 2020, the Medicare reimbursement cuts that would have occurred under PAMA in 2021 were delayed by one year. In 2021, Dx realized an increase of approximately $0.3 million in PFS revenue as a result of the provisions included in the Omnibus Appropriations and Coronavirus Relief Package. In 2021, Dx realized an additional increase of approximately $5.8 million in aggregate Medicare reimbursement associated with the suspension of sequestration through December of 2021, as a result of provisions included in the Omnibus Appropriations and Coronavirus Relief Package that were extended as a result of an Act to Prevent Across-the-Board Direct Spending Cuts.

On December 10, 2021, President Biden signed into law the Protecting Medicare and American Farmers from Sequester Cuts Act, which delayed by one additional year the data reporting requirements and Medicare reimbursement cuts that would have occurred under PAMA in 2022, resulting in a 0% update to the CLFS in 2022. In 2022, Dx realized a decrease of approximately $0.4 million in PFS revenue driven by reductions in reimbursement for flow cytometry procedures and a decrease of approximately $10.0 million in aggregate Medicare reimbursement associated with the phased in reinstitution of sequestration as a result of provisions included in the Protecting Medicare and American Farmers from Sequester Cuts Act.

The Protecting Medicare and American Farmers from Sequester Cuts Act also included mitigations to several other non-PAMA Medicare cuts in addition to delaying Medicare reimbursement cuts under PAMA. It delayed the 4% Medicare cuts that would otherwise have occurred in 2022 under statutory “pay-as-you-go,” or PAYGO, rules to offset the cost of the American Rescue Plan Act by one year. In addition, it delayed the resumption of the 2% Medicare sequestration until April 1, 2022, and reduced to 0.75% the previous 3.75% reduction to PFS reimbursement that was scheduled for 2022. To offset the cost, the Medicare sequestration was increased to 2.25% for January through June of 2030, and to 3.0% for July through December 2030.

On December 29, 2022, President Biden signed into law the Consolidated Appropriations Act, 2023, which delayed by one additional year the data reporting requirements and Medicare reimbursement cuts that would have occurred under PAMA in 2023, resulting in a 0% update to the CLFS for 2023. The Consolidated Appropriations Act, 2023 also included mitigations to several other non-PAMA Medicare cuts in addition to delaying Medicare reimbursement cuts under PAMA. It delayed until 2025 the 4% Medicare cuts that would otherwise have been effective January 1, 2023 under PAYGO rules. In addition, it mitigated PFS cuts in 2023 and 2024 to by 2.5% and 1.25%, respectively, that would otherwise have been a decrease of 4.47% in 2023 based on the conversation factor put forward in the 2023 Medicare PFS Final Rule. To offset the cost, it extended the 2% Medicare sequestration through the first six months of 2032 and set the sequestration percentage at 2% in fiscal years 2030 and 2031.

On November 16, 2023, President Biden signed into law the Further Continuing Appropriations and Other Extensions Act, which delayed by one additional year the data reporting requirements and Medicare reimbursement cuts that would have occurred under PAMA in 2024, resulting in a 0% update to the CLFS for 2024.

In 2024, Dx anticipates a net PFS revenue decrease of approximately 0.7% ($1.0 million) from the 2024 Medicare PFS Final Rule, driven by a 3.4% decrease to the PFS conversion factor along with changes in relative value units (RVUs) for PFS procedures. The blood draw rate change was not mentioned in the 2024 Medicare PFS Final Rule, however the rate did receive a consumer price index adjustment resulting in an increase from $8.57 to $8.83 or approximately 3%. Congress is considering legislation that would mitigate these cuts if enacted.

Pursuant to PAMA as amended, for 2025 through 2027, a CLFS test price cannot be reduced by more than 15.0% per year (excluding non-PAMA reimbursement changes). CLFS rates for 2028 and subsequent periods will not be subject to phase-in limits. The phase-in of rates for Clinical Diagnostic Laboratory Tests (CDLTs) established in 2018 will resume in 2025. New CLFS rates will be established in 2026 based on data from 2019 to be reported in 2025. New CLFS rates will be established in 2029 based on data from 2027 to be reported in 2028. CLFS rates for Advanced Diagnostic Laboratory Tests will be updated annually.

Index

The American Clinical Laboratory Association (ACLA) filed a federal civil action in 2017 challenging the legal basis for the data collection methodology CMS used to derive the data from which the median prices were calculated. On July 15, 2022, the U.S. Court of Appeals for the D.C. Circuit ruled in favor of ACLA on the merits, finding that CMS harmed laboratories by collecting data in an arbitrary and capricious manner, but refused to grant relief due to PAMA’s statutory bar on judicial review of establishment of the rates.

Since the initial data collection, CMS has revised its PAMA regulations to increase the number of hospital outreach labs that will be required to report private market data in future collections. Reports by the U.S. Government Accountability Office (GAO), the HHS Office of Inspector General (OIG), and the Medicare Payment Advisory Commission (MedPAC) on PAMA implementation have identified certain instances of actual or potential increased Medicare expenditures under PAMA, as well as potential alternative methodologies for data collection under PAMA, which could result in further efforts to amend PAMA by Congress.

ACLA has continued to work with Congress on potential legislative reform of PAMA, which if adopted could reduce the negative impact of PAMA as currently implemented by CMS. Under the Laboratory Access for Beneficiaries Act, MedPAC was required to conduct a study and make recommendations to Congress on ways to improve data collection, reporting, and rate setting under PAMA to achieve, in a less burdensome manner, CLFS rates that accurately and fairly reflect private market rates. MedPAC's June 2021 report to Congress included an analysis of potential statistical sampling methodologies that could accomplish that objective, and ACLA incorporated the concept in PAMA reform proposals to Congress. On June 22, 2022, the Saving Access to Laboratory Services Act (SALSA), was introduced in both the U.S. Senate and the U.S. House of Representatives to provide for permanent reform of PAMA incorporating many of ACLA’s proposals. SALSA was re-introduced in the US. Senate on March 28, 2023 and in the U.S. House of Representatives on March 29, 2023. The Company supports the ongoing efforts to prevent or lessen the negative impact of the changes to the CLFS pursuant to PAMA, and the full impact of those efforts, but what the long-term effect will be on the CLFS rates is not yet known.

Further healthcare reform could occur in 2024, including changes to the Patient Protection and Affordable Care Act (ACA) and Medicare reform, as well as administrative requirements that may continue to affect coverage, reimbursement, and utilization of laboratory services in ways that are currently unpredictable.

In addition, market-based changes have affected and will continue to affect the clinical laboratory business. Reimbursement from commercial payers for diagnostic testing may shift away from traditional, fee-for-service models to alternatives, including value-based, bundled pay-for-performance, and other risk-sharing payment models. The growth of the managed care sector and consolidation of MCOs present various challenges and opportunities to Dx and other clinical laboratories. Dx's ability to attract and retain MCO customers has become even more important as the impact of various healthcare reform initiatives continues, including expanded health insurance exchanges and ACOs.

The Company serves many MCOs. These organizations have different contracting philosophies, which are influenced by the design of their products. Some MCOs contract with a limited number of clinical laboratories and engage in direct negotiation of rates. Other MCOs adopt broader networks with generally uniform fee structures for participating clinical laboratories. In some cases, those fee structures are specific to independent clinical laboratories, while the fees paid to hospital-based and physician-office laboratories may be different, and are typically higher. MCOs may also offer managed Medicare or managed Medicaid plans. In addition, some MCOs use capitation rates to fix the cost of laboratory testing services for their enrollees. Under a capitated reimbursement arrangement, the clinical laboratory receives a per-member, per-month payment for an agreed upon menu of laboratory tests, or based upon the proportionate share earned by the clinical laboratory from a capitation pool. When the agreed upon reimbursement is based solely on an established rate per member, revenue is not impacted by the volume of testing performed. Under a capitation pool arrangement, the aggregate value of an established rate per member is distributed based on the volume and complexity of the procedures performed by laboratories participating in the agreement. For the year ended December 31, 2023, capitated contracts with MCOs accounted for approximately $369.9 million, or 3.9%, of Dx's revenues.

In addition to reductions in test reimbursement, the Company also anticipates potential declines in test volumes as a result of increased controls over the utilization of laboratory services by Medicare, Medicaid, and other third-party payers, particularly MCOs. MCOs are implementing, directly or through third parties, various types of laboratory benefit management programs, which may include laboratory networks, utilization management tools (such as prior authorization and/or prior notification), and claims edits, which impact coverage and reimbursement of clinical laboratory tests. Some of these programs address clinical laboratory testing broadly, while others are focused on certain types of testing, including molecular, genetic, and toxicology testing. In addition, continued movement by patients into consumer-driven health plans may have an impact on the utilization of laboratory testing.

Helping to balance the overall negative market changes regarding reimbursement discussed above, the Company believes that the volume of clinical laboratory testing is positively influenced by several factors, including an increase in the number and

types of tests that are readily available (due to advances in technology and increased cost efficiencies) for the diagnosis of disease, and the general aging of the U.S. population. Periodic infectious disease outbreaks such as the SARS-CoV-2 virus also have the potential to generate additional testing volume in the future, and enhance stakeholders’ appreciation for the value of laboratory testing in combating future potential outbreaks. Dx believes that its enhanced and growing menu of tests, focus on high-potential clinical areas, leading position with companion diagnostics, broad geographic footprint, and operating efficiency make it well positioned for growth due to a number of market factors, primarily related to a continued drive to improve outcomes and reduce costs across the healthcare system, including but not limited to greater price transparency required under “surprise billing” laws and regulations requiring disclosure of hospital charges.

Rewards

The Company operates in a complex, global, and dynamic life sciences industry and believes that its compensation and benefits programs must be competitive and flexible to attract and retain the caliber of talent needed for the sustained growth and success of the business.

The Company regularly monitors market activity and employee movement within and outside of the life sciences industry to maintain competitiveness. In 2023, the Company invested more than $20 million in special bonuses to more than 28,000 non-executive employees globally in patient and client-facing roles to recognize employee commitment and contributions throughout the COVID-19 pandemic. In addition, the Company awarded $96 million in annual merit increases to recognize its talent and foster pay competitiveness in the market.

Employee Wellbeing

The Company believes that its investments in compensation and employee wellbeing are crucial to maintaining competitive positioning and a productive, engaged workforce. The Company fulfills its commitment to employee wellbeing by investing in a variety of tools and resources to support its employees’ physical, emotional, and financial well-being.

Whether it is through zero-cost telehealth visits for medical, dermatological, and behavioral treatment as part of the Company's medical plans in the U.S., employer matching 401(k) contributions and financial wellness workshops, or custom stress management strategies for teams around the world through its Healthy Huddles program, the Company continues to offer various ways for employees to focus on their wellbeing.

The Company also understands the continuing urgency around mental wellbeing and the importance of providing resources to support employees and their families. In 2023, the Company expanded its wellbeing strategy to include a dedicated U.S. mental wellbeing specialist who oversees all mental wellbeing initiatives. Mental Health First Aid Training was completed by 425 of the Company's Human Resources and top leaders at the Company, and the program will expand to others in 2024. Sixty-six virtual sessions, called Healthy Huddles, were leveraged by leaders for their teams across the globe, with sessions such as guided meditations and stretch breaks. In partnership with employee assistance program (EAP) providers, the Company recognized World Mental Health Day in October 2023 with events and education throughout the whole month, including a global panel event featuring employees who shared their personal stories and struggles. An additional 32 live mental wellbeing educational webinars were shared worldwide, to help reduce stigma and enhance awareness. The addition of free behavioral health services via telemedicine led to a significant increase in utilization for U.S. members of the Company's medical plans.

Additional efforts in support of employee wellbeing include:

•Reducing the cost of monthly medical insurance contributions by $240 per year for approximately 19,000 employees in the U.S. earning less than $50,000 per year who participate in Company medical plans;

•Shifting the focus for annual wellness screenings to a more wholistic approach that emphasizes the importance of identifying metabolic conditions that can increase the risk of heart attack, stroke, and diabetes. Over 30,000 U.S. employees and their covered spouses and domestic partners received medical plan contribution discounts of up to $4,560;

•Providing up to $1,000 in health reimbursement account contributions, available to approximately 31,000 employees and their spouses or domestic partners to encourage health and wellness education and activities; and

•Reimbursing up to $300 in fitness-related expenses for approximately 15,000 employees across the U.S. and Canada.

The Company's No Charge Laboratory Testing program enables eligible U.S. employees and their covered dependents to offset any outstanding balance for most lab work sent to a Company facility or patient service center, following insurance claim processing. Additionally, the Company offers global initiatives to encourage sustainable transportation through programs such as discounted transportation vouchers, reduced-cost bicycle leases, and mileage reimbursement for bicycle commuters, with benefits varying by country.

Index

To enable its employees to establish ownership in the Company, the Company offers an Employee Stock Purchase Plan (ESPP) that allows U.S. employees to purchase Common Stock at a 15% discount. The plan was extended to an additional 5,000 employees in Canada and the U.K. in 2022 and 2023 to foster broader employee participation in the plan. Over 10,000 employees took advantage of the ESPP in 2023.

Development and Training

As an organization that pursues answers to the world’s most critical healthcare questions, the Company supports its employees with a work environment that emphasizes continuous learning and development. Through these learning and development opportunities, the Company encourages learning, growth and innovation, to deliver better patient care and new solutions for its customers. The Company provides professional skills training and role specific training, along with formal and informal mentoring, job rotations, and opportunities for temporary assignments. The Company onboards and develops new hires through extensive training provided by a dedicated team of technical skill trainers with different departments and functions.

2023 Training Milestones:

•Provided more than 13,700 courses, many of which are available virtually within the global learning management system;

•Completed over 1.3 million hours of training, primarily consisting of regulatory and technical training;

•Offered mentoring programs that 2,400 employees participated in as either mentors or mentees, the largest number of participants to date in the program’s 15-year history; and

•Completed more than 9,400 hours of professional development.

As a leader in science, the Company has almost 12,000 science-based jobs and leverages several internal scientific forums to help scientists at all levels of experience continuously learn, innovate, and advance the healthcare industry. From scientific councils to a Molecular Tumor Board to Science Micro Bites, those in scientific roles are staying current in their fields of study, sharing their knowledge with others, and helping to expand the skills and experience of their colleagues.

An example of scientific employees sharing knowledge and experience is the Lab Exchange Program that was launched in 2023. Through this program, colleagues in technical positions in our BLS and Dx labs are able to experience a two-week domestic or international assignment at one of five host site labs from the other business segment to which they normally are assigned, during which they are immersed in learning the processes and technologies used at that site. This helps encourage collaboration across business segments, and exposes both the employees participating in the program and the laboratory staff at their host site with greater knowledge of and exposure to the Company's full scope of laboratory operations.

The Company’s ongoing investment in the development of its people stems from a continuing commitment to build a stronger, more diverse team. In addition to traditional tuition reimbursement, over the past three years, Labcorp Education Advantage has actively supported employees in their pursuit of higher education by covering tuition costs for healthcare or life science degree programs that contribute to their career advancement within the Company. To date, more than 1,100 employees have benefited from this initiative, while also avoiding student loan debt.

Company Recognition for Focus on Employee Development

The Company was once again a proud recipient of the 2023 Princess Royal Training Awards (U.K.), honoring the work done through apprenticeship programs and initiatives to develop leaders. The 2023 award recognized the Company's partnership with the University of Leeds to provide a master's course in Biopharmaceutical Development. The Princess Royal Training Awards are offered to employers in the United Kingdom who can prove that their outstanding training and skills development programs have resulted in exceptional benefits for their business.

The Company was also ranked #1 in the Medical Care Facilities Sector and #35 out of all Fortune 500 companies surveyed in the 2023 American Opportunity Index. A joint project from the Burning Glass Institute, the Harvard Business School Project on Managing the Future of Work, and the Schultz Family Foundation, the index uses independent data to measure how well Fortune 500 companies drive economic mobility and positive career advancement for their employees. The Company aspires to create a workplace where employees can grow and discover more while advancing their career.

Health and Safety

The nature of the Company's business requires employees to work directly with patients and animals. This includes the handling, processing, and testing of human or animal specimens on a daily basis. As the health and safety of employees is a primary concern, the Company has established numerous employee health and safety protocols, including engineering and administrative controls, policies, procedures, processes, and training to minimize the potential for, and the severity of, work-related injuries and illnesses.

Index

In 2023, the Company reduced its work-related injury rate per 100 employees 13.6% over 2022. The Company's maintained work-related lost work injury rate per 100 employees increased by 25% over 2022, to 0.5%. The Company completed a Corporate EHS Audit on 11 significant laboratory facilities, allowing it to assess locations against common expectations and performance criteria. The Company also completed nearly 120,000 safety training sessions covering topics that included bloodborne pathogen, chemical safety, and employee health and safety general awareness. As previously reported, the Company modified the audit format in response to COVID-19 so that it could be effectively performed virtually, with the added benefit of reducing audit travel-related greenhouse gas emissions.

Community Engagement

The Labcorp Charitable Foundation, a private, charitable 501(c)(3) organization established by the Company, invested in more than 140 programs in 2023 that align with the Company’s strategic mission to improve health and improve lives in the areas of health, education, and community across the globe. The Foundation supports efforts to increase access to health services and create equitable opportunities for underserved populations across the globe.

Colleagues around the globe are invited to participate in the Company’s annual Employee Giving Campaign. Through the campaign, colleagues had the opportunity to donate to one or more of seven selected charities: the American Cancer Society, American Heart Association, American Diabetes Association, American Red Cross (Disaster Relief), United Way, the National Urban League, and Project HOPE. Employee contributions support these charities to provide needed services in their local communities and around the globe. The Labcorp Charitable Foundation offers a match opportunity for contributions made through the campaign.

In addition, the Company's employees took advantage of opportunities to support charitable causes and make a positive impact in their communities. For example, in honor of the life and legacy of Dr. Martin Luther King, Jr., colleagues participated in the “Cards of Encouragement” campaign, a global initiative to lift the spirits of hospitalized children and their families. With the help of Cards for Hospitalized Kids, close to 8,000 cards were distributed to children and their families staying at Ronald McDonald Houses or receiving treatment at nonprofit children’s hospitals. The Labcorp Charitable Foundation made a financial donation to the 39 supported charities.

The Company's global colleagues also support the local communities where they live and work. In observation of Childhood Cancer Awareness Month, Company colleagues in Geneva, Switzerland supported ARFEC (Association Romande des Familles d’Enfants atteints d’un Cancer) to benefit hospitalized children and their families through toy drives, the creation and sale of a calendar, and participation in the Geneva 20-kilometer race.

Dynacare, a Company subsidiary based in Canada, teamed up with Diabetes Canada to organize the #Dyncare4Diabetes campaign for the second consecutive year. The campaign raised awareness of diabetes and provides accessible and free testing for at risk individuals. In addition to offering free hemoglobin A1C testing at all Dynacare laboratory locations across the Greater Toronto Area and at mobile community clinics, Dynacare donated 50 cents to Diabetes Canada for every individual that participated in the campaign, up to a total of $25,000.

Customers

The Company provides its services to a broad range of customers across Dx and BLS. The primary customer groups serviced by the Company include:

•Payers - Health Plans and Employers. The Company serves many health plans, including MCOs, employer plans, and other health insurance providers, each of which operates on a national, regional, or local basis. In certain locations, health plans may delegate to independent physician associations (IPAs) or other alternative delivery systems (e.g., ACOs) the ability to negotiate for services on behalf of certain members.

•Pharmaceutical, Biotechnology, Medical Device, and Diagnostics Companies. The Company provides services to hundreds of pharmaceutical, biotechnology, medical device, and diagnostics companies, ranging from the world's largest multi-nationals to emerging, small and mid-market companies.

•Physicians, Large Provider Organizations, and Other Healthcare Providers. Physicians and other healthcare providers who are authorized to order clinical laboratory testing for their patients are a primary source of requests for Dx's testing services. These physicians and other providers may practice in a range of settings, including small medical practices, community-based clinics, and large, multidisciplinary organizations.

•Hospitals and Health Systems. The Company provides hospitals and health systems with services ranging from core and specialty testing to supply chain and technical support services, and the opportunity to be a research partner for participation in studies and clinical trials with BLS. In some cases, a hospital’s on-site laboratory may be operated or managed by an outside contractor or independent laboratory, including the Company.

Index

•Other Customers. The Company serves a broad range of other customers, including, but not limited to, governmental agencies, employers, patients and consumers, contract research organizations (CROs), crop protection and chemical companies, academic institutions, independent clinical laboratories, and retailers.

Sales, Marketing, and Customer Service

The Company offers its services through a sales force focused on serving the specific needs of customers in different market segments. The Company's sales force is responsible for both new sales and for customer retention and relationship building.

For Dx, these market segments have different representatives focused on each segment in order to better understand and respond to the unique needs of each segment. These include clinical areas, such as primary care, oncology, women's health, autoimmune diseases, neurology, infectious diseases, endocrinology, gastroenterology, rheumatology and other specialties; payers, such as ACOs, MCOs, and employers; and customers, such as physicians and physician organizations and hospitals and health systems. The BLS global sales organization provides customer coverage across the pharmaceutical, biotechnology, and medical device industries for services including lead optimization, preclinical safety assessment, analytical services, clinical trials, central laboratories, biomarkers, companion diagnostics, and technology solutions. As part of the Company's ongoing strategic priority to maximize the value of its unique leadership in both diagnostics and drug development, sales representatives from each business segment work together on outreach to potential customers of both businesses, including hospitals and health systems that may purchase testing and participate in clinical trials, or pharmaceutical, biotechnology, or medical device companies whose studies may benefit from use of Dx’s specialty testing, companion diagnostics, and network of PSCs.

Market Opportunity

The Company believes that in 2023, the U.S. clinical laboratory testing industry generated revenues of more than $80 billion. The clinical laboratory industry consists primarily of three types of providers: hospital-based laboratories, physician-office laboratories, and independent clinical and anatomical pathology laboratories, such as those operated by Dx.

The clinical laboratory business is intensely competitive, and the Company believes that both competition and consolidation in the clinical laboratory business will continue. CMS has estimated that, as of February 2024, there were nearly 320,000 clinical laboratories of all types, including approximately 9,200 hospital-based laboratories, just under 123,000 physician-office laboratories, and 9,063 independent clinical and anatomic pathology laboratories in the U.S. Dx competes with all of those laboratories. In addition, an increasing number of health system laboratories have been expanding their operations and business, resulting in greater competition for testing from physicians within those systems and from unaffiliated physicians in the health system laboratories’ service areas.

Dx believes that the selection of a laboratory is primarily based on the following factors, all of which the Company believes it competes favorably in:

•brand strength and reputation;

•leadership in science, technology, and innovation;

•patient satisfaction levels;

•national scale, and local presence with access to testing within 10 miles of most households;

•quality, timeliness, and consistency in reporting test results;

•contractual relationships with MCOs;

•number and type of tests performed;

•connectivity solutions offered; and

•pricing of the laboratory’s services.

In addition to the factors listed above, the Company believes that the operational and economic efficiencies provided by its integrated service and logistics network, large-scale automated testing, and regular introduction of new technologies will allow the Company to compete effectively with other providers of laboratory services.

BLS

The Company believes that in 2023, the global pharmaceutical industry spent more than $200 billion on R&D. Drug development services businesses like BLS typically derive most of their revenue from R&D, as well as marketing expenditures, of the pharmaceutical, biotechnology, and medical device industries.

Outsourcing of R&D services to CROs and other service providers has increased in the past, and is expected to continue increasing in the future. Increasing pressures to improve return on investment, to increase R&D productivity, to stay abreast of scientific advances and to comply with stringent government regulations and attempts to reduce and control the price of

Index

prescription drugs have all contributed to this outsourcing which provides clients with flexibility in aligning resources to demand. In the face of mounting complexity, the investment and amount of time required to develop new products are significant and have been increasing. These trends create opportunities for BLS and other companies providing drug development services that can help make the development process more efficient.

The drug development industry has many participants ranging from hundreds of small providers to a limited number of large companies with global capabilities. BLS competes against these small and large businesses, as well as in-house departments of pharmaceutical, biotechnology, medical device, and diagnostic companies, and to a lesser extent, selected academic research centers, universities, and teaching hospitals.

BLS believes that customers selecting a drug development partner often consider the following factors, all of which the Company believes it competes favorably in:

•reputation for quality and regulatory compliance;

•efficient, timely performance;

•expertise and experience in operations;

•application of technology and innovation;

•specific therapeutic and scientific expertise;

•data and analytical capabilities;

•ability to enhance patient recruitment;

•scope of service offerings;

•strengths in various geographic markets;

•price;

•quality of facilities;

•quality of relationships, including investigator and patient;

•ability to manage large-scale clinical trials both domestically and internationally;

•size and scale;

•ability to support decentralized clinical trials;

•ability to develop companion diagnostics; and

•access to talent.

Quality

Dx and BLS have comprehensive quality systems and processes appropriate for their respective businesses. The Company's quality programs are overseen by Dx's National Office of Quality, BLS’s Global Regulatory Compliance and Quality Assurance Unit, BLS's central laboratory services expanded laboratory management services department, and the Company's global supply chain management department and project management staff. The Company has procedures for monitoring its internal performance, as well as that of its vendors, suppliers, and other key stakeholders. In addition, various groups and departments within the Company provide oversight to monitor and control vendor products and performance, and play an essential role in the Company’s approach to quality through improvements in processes and automation.

Virtually all facets of the Company’s services are subject to quality programs and procedures, including accuracy and reproducibility of tests, turnaround time, customer service, marketing communications, data integrity, patient satisfaction, and billing. The Company’s quality programs include measures that compare current performance against desired performance goals to monitor critical aspects of service to its customers and patients. This includes licensing, credentialing, training, and competency assessment of professional and technical staff, and internal auditing. In addition to the Company's own quality programs, the Company’s laboratories, facilities and processes are subject to on-site regulatory agency inspections and accreditation evaluations, in addition to surveys and proficiency testing, by local or national government agencies, independent external accrediting programs, and inspections and audits by customers.

Thirty-three of the Company's laboratories have received ISO 15189, ISO 13485 and/or ISO 141791 accreditation, demonstrating that they meet international standards for quality and technical competence.

Information Systems

The Company is committed to developing and commercializing technology-enabled solutions to support its operations and provide better care. The Company operates standard platforms for its core business services and its financial and reporting systems. These standard systems provide consistency within workflows and information as well as a high level of system availability, security, and stability. The primary laboratory systems include standardized support for molecular diagnostics, digital pathology, and enhanced specialty laboratory solutions. The Company's centralized information systems are responsible for operational efficiencies, enabling the Company to achieve consistent, structured, and standardized operating results and effective patient care.

Index

The information systems used by Dx and BLS are discussed in more detail in the sections dedicated to each of those segments. The Company's cybersecurity processes and systems are discussed in more detail under “Cybersecurity” in Item 1C.

For several years the Company has deployed artificial intelligence and machine learning tools (AI) to supplement its existing data analysis projects and support greater efficiency in its operations. The Company is currently evaluating and testing various further applications of AI, while also implementing policies and processes to provide appropriate governance over the use of AI by the Company.

Intellectual Property Rights

The Company relies on a combination of patents, trademarks, copyrights, trade secrets, and nondisclosure and non-competition agreements to establish and protect its proprietary technology. The Company has filed and obtained numerous patents in the U.S. and abroad, and regularly files patent applications, when appropriate, to establish and protect its proprietary technology. Occasionally, the Company also licenses U.S. and non-U.S. patents, patent applications, technology, trade secrets, know-how, copyrights or trademarks owned by others. The Company believes, however, that no single patent, technology, trademark, intellectual property asset or license is material to its business as a whole.

Patents covering the Company's technologies are subject to challenges. Issued patents may be successfully challenged, invalidated, circumvented, or declared unenforceable so that patent rights would not create an effective competitive barrier. In addition, the laws of some countries may not protect proprietary rights to the same extent as do the laws of the U.S.

Parties may file claims asserting that the Company's technologies infringe on their intellectual property. The Company cannot predict whether parties will assert such claims against it, or whether those claims will harm its business. If the Company is forced to defend against such claims, the Company could face costly litigation and diversion of management’s attention and resources. As result of such disputes, the Company may have to develop costly non-infringing technology or enter into licensing agreements. These agreements, if necessary, may require financial or other terms that could have an adverse effect on the Company's business and financial condition.

Regulation and Reimbursement

General

Because the Company operates in a number of distinct environments and in a variety of locations worldwide, it is subject to numerous, and sometimes overlapping, regulatory requirements. Both the clinical laboratory and the drug development businesses are subject to significant governmental regulation at the international, national, state and local levels. As described below, these regulations concern licensure and operation of clinical laboratories, claims submission and reimbursement for laboratory services, healthcare fraud and abuse, drug development services, security and confidentiality of health information, quality, and environmental and occupational safety.

Regulation of Clinical Laboratories

Virtually all clinical laboratories operating in the U.S. must be certified by the federal government or by a federally approved accreditation agency. In most cases, that certification is regulated by CMS through CLIA, which requires that applicable clinical laboratories meet quality assurance, quality control, and personnel standards. Laboratories also must undergo proficiency testing and are subject to inspections. Clinical laboratories in locations other than the U.S. are generally subject to comparable regulation in their respective jurisdictions.

Standards for testing under CLIA are based on the complexity of the tests performed by the laboratory, with tests classified as “high complexity,” “moderate complexity,” or “waived.” Laboratories performing high-complexity testing are required to meet more stringent requirements than moderate-complexity laboratories. Laboratories performing only waived tests, which are tests determined by the FDA to have a low potential for error and requiring little oversight, may apply for a certificate of waiver exempting them from most CLIA requirements. All major and many smaller Company facilities hold CLIA certificates to perform high-complexity testing. The Company's remaining smaller testing sites hold CLIA certificates to perform moderate-complexity testing or a certificate of waiver. The sanctions for failure to comply with CLIA requirements include suspension, revocation, or limitation of a laboratory's CLIA certificate, which is necessary to conduct business; cancellation or suspension of the laboratory's approval to receive Medicare and/or Medicaid reimbursement; as well as significant fines and/or criminal penalties. The loss or suspension of a CLIA certification, imposition of a fine or other penalties, or future changes in the CLIA law or regulations (or interpretation of the law or regulations) could have a material adverse effect on the Company.

The Company is also subject to state and local laboratory regulation. CLIA provides that a state may adopt laboratory regulations different from or more stringent than those under federal law, and a number of states have implemented their own laboratory regulatory requirements. State laws may require that laboratory personnel meet certain qualifications, specify certain quality controls, or require maintenance of certain records.

Index

The Company believes that it is in compliance in all material respects with all laboratory requirements applicable to its laboratories operating both within the U.S. and in other countries. The Company's laboratories have continuing programs to maintain operations in compliance with all such regulatory requirements, but no assurances can be given that the Company's laboratories will pass all future licensure or certification inspections.

FDA and Other Regulatory Agency Laws and Regulations

Various regulatory agencies, including CMS and the FDA in the U.S., regulate the development, testing, manufacturing, labeling, advertising, marketing, distribution, storage, import, export, performance, and surveillance of diagnostic and therapeutic products and services, including certain products and services offered by the Company and the development of therapeutic products that comprise the majority of BLS’s business. The FDA and other regulatory agencies periodically inspect and review the manufacturing processes and product performance of diagnostic and therapeutic products, while CMS, certain state programs, and accreditation entities inspect and review the facilities, personnel, and procedures of clinical laboratories and their laboratory operations. The FDA and other regulatory agencies also periodically inspect test facilities that perform tests on samples from preclinical studies and on human subjects enrolled in such clinical studies of drugs, biologics, and medical devices. These agencies have the authority to take various administrative and legal actions for noncompliance, such as fines, withdrawal of product approval, warning or untitled letters, seizures, recalls, injunctions, and other civil and criminal sanctions.

Since 2014, there have been ongoing discussions and advocacy between stakeholders, including the clinical laboratory industry, the FDA, and Congress, about potential FDA regulation of laboratory-developed tests (LDTs), which are assays developed and performed in-house by clinical laboratories and can be made available to the public without pre-market review by the FDA, with limited exceptions that require LDTs to follow pre-market requirements, such as during the COVID-19 public health emergency.

On September 29, 2023, the FDA released a proposed rule to regulate LDTs as medical devices, which was formally published in the Federal Register on October 3, 2023. The proposed rule seeks to make explicit that in vitro diagnostic products (IVDs) are devices under the Federal Food, Drug and Cosmetic Act, including when the manufacturer of the IVD is a clinical laboratory. In conjunction with this proposed rule and issuance of new regulations, the FDA is proposing a policy by which FDA would phase out its general enforcement discretion approach for LDTs over a period of four years after the publication of a final rule so that LDTs manufactured by a clinical laboratory would, over the transition period, fall under the existing enforcement approach as for IVDs. The proposed rule would not grandfather existing tests or exempt academic medical centers or small laboratories, but the FDA has requested public comments on whether it should include those features in a final rule. ACLA disputes FDA’s assertion that LDTs are medical devices, and filed comments in December 2023 opposing the proposed rule and urging its withdrawal based on both policy and legal grounds. In December 2023, the Company also filed comments opposing the proposed rule and urging its withdrawal for the reasons set forth in ACLA’s comments. Both ACLA and the Company have urged FDA to continue working with Congress and stakeholders toward enactment of appropriate legislation instead of pursuing device regulation of LDTs through a proposed rulemaking.

There are similar national and regional regulatory agencies, and regulations, in the jurisdictions outside of the U.S. in which the Company operates. For example, the European Union In Vitro Diagnostics Regulation, which became applicable May 26, 2022, established a new legislative framework for in vitro diagnostic devices including a rule-based classification and quality and safety standards. In addition, both Switzerland and the United Kingdom are implementing new legislative frameworks similar to the EU IVDR.

BLS’s laboratory facilities and Dx's clinical laboratory facilities that perform testing services in support of preclinical studies and clinical trials, must conform to a range of standards and regulations, including good laboratory practice (GLP) and good clinical practice (GCP), current good manufacturing practice (cGMP), human subject protection and investigational product exemption regulations, and quality system regulation (QSR) requirements, as applicable. The preclinical and clinical testing intended to support applications for research or marketing, and the studies that the Company conducts, are subject to periodic inspections by the FDA, as well as other regulatory agencies in the jurisdictions outside the U.S. in which the Company operates, which may include, without limitation, the Medicines and Healthcare products Regulatory Agency (MHRA) in the U.K., the European Medicines Agency, the National Medical Products Administration in China, and the Pharmaceuticals and Medical Devices Agency in Japan, to determine compliance with GLP, GCP, and cGMP, as well as other applicable standards and regulations. If a regulatory agency determines during an inspection that the Company’s equipment, facilities, laboratories, operations, or processes do not comply with applicable regulations and GLP, GCP and/or cGMP standards, the regulatory agency may issue a formal notice (e.g., FDA Form 483), which may be followed by a warning letter or other enforcement actions if observations are not addressed satisfactorily. Noncompliance may result in, among other things, unanticipated compliance expenditures, the regulatory agency seeking civil, criminal or administrative sanctions and/or remedies against the Company, including suspension of its operations, and related customer contractual claims and other liabilities.

Index

The FDA Modernization Act 2.0 was enacted in December 2022 as Section 3209 of the Consolidated Appropriations Act, 2023. This Act amended Section 505 of the Federal Food, Drug and Cosmetic Act to clarify the methods manufacturers and sponsors can use to investigate the safety and efficacy of a drug or the toxicity of a biosimilar biologic product to include tests on animals, as well as certain tests that are not performed on animals. Specifically, the Act replaces a statutory reference to “tests on animals” as a viable option for preclinical testing with a reference to “nonclinical tests”, which includes animal testing, cell-based assays, microphysiological systems, or bioprinted or computer models. The Act does not eliminate animal testing or require the use of non-animal models. FDA previously had the authority to allow non-animal data to be considered during safety and efficacy reviews of new drugs and had previously issued related guidance. However, many procedures intended to reduce animal tests are still in various stages of development. Such alternative methodologies must first be validated before FDA will approve of their use instead of validated animal models, so the practical impact of the Act is likely to be limited for some time.

Additionally, certain BLS services and activities, such as chemistry, manufacturing, and controls (CMC) services, must conform to cGMP. BLS is subject to periodic inspections by the FDA and the MHRA, as well as other regulatory agencies in the jurisdictions outside the U.S. in which the Company operates, in order to assess, among other things, cGMP compliance. If a regulatory agency identifies deficiencies during an inspection, it may issue a formal notice, which may be followed by a warning letter if observations are not addressed satisfactorily. Failure to maintain compliance with cGMP regulations and other applicable requirements of various regulatory agencies could result in, among other things, fines, warnings or untitled letters, unanticipated compliance expenditures, suspension of manufacturing, enforcement actions, product seizures or recalls, injunctions, or criminal prosecution.

Some Dx products are regulated by the FDA and other similar national regulatory agencies as medical devices. The FDA defines a medical device in part as an instrument, apparatus, implement, machine, contrivance, implant, in vitro reagent, or other similar or related article which is intended for the diagnosis of disease or other conditions or in the cure, mitigation, treatment, or prevention of disease in man. FDA regulates the development, testing, manufacturing, marketing, post‑market surveillance, distribution, advertising, and labeling of products classified as medical devices separate from clinical diagnostic testing services offered under CLIA requirements. FDA regulatory requirements include: all of the relevant elements of the QSR, which requires manufacturers to follow stringent design, testing, control, documentation, and other quality assurance procedures; labeling regulations; restrictions on promotion and advertising; Medical Device Reporting regulations, which require the manufacturer to report to the FDA if its device may have caused or contributed to a death or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were to recur; the Reports of Corrections and Removals regulations, which require manufacturers to report certain recalls and field actions to the FDA;, and other post-market requirements.

To ensure compliance with regulatory requirements, medical device manufacturers are subject to market surveillance and periodic, pre-scheduled and unannounced inspections by the FDA. Failure to comply with applicable regulatory requirements can result in enforcement action by the FDA, which may include sanctions, operating restrictions, partial suspension, or total shutdown of production, refusal to grant clearance or approvals of new devices, withdrawal of clearance or approval, and civil or criminal prosecution.

Animal Welfare Laws and Regulations

The conduct of animal research at BLS’s facilities in the U.S. must be in compliance with the Animal Welfare Act (AWA), which governs the care and use of warm-blooded animals for research in the U.S., other than laboratory rats, mice, and chickens, and is enforced through periodic inspections by the U.S. Department of Agriculture (USDA). The AWA establishes facility standards regarding several aspects of animal welfare, including housing, ventilation, lighting, feeding and watering, handling, veterinary care, and recordkeeping. BLS complies with licensing and registration requirement standards set by the USDA and similar agencies in foreign jurisdictions such as the European Union, the U.K., and China for the care and use of regulated species. If the USDA determines that BLS’s equipment, facilities, laboratories or processes do not comply with applicable AWA standards, it may issue an inspection report documenting the deficiencies and setting deadlines for any required corrective actions. The USDA may impose fines, suspend and/or revoke licenses and registrations, or confiscate research animals. Other countries where the Company conducts business have similar laws and regulations with which the Company must also comply. In addition, certain of BLS’s animal-related activities may be subject to regulation by the U.S. Centers for Disease Control and Prevention (CDC), the Office of Laboratory Animal Welfare of the National Institutes of Health, the U.S. Fish and Wildlife Service, and similar organizations in other jurisdictions in which the Company operates.

Payment for Clinical Laboratory Services

In 2023, Dx derived approximately 10.6% of its revenue directly from traditional Medicare and Medicaid programs. In addition, Dx's other commercial laboratory testing business that is not directly related to Medicare or Medicaid nevertheless depends significantly on continued participation in these programs and in other government healthcare programs, in part

because customers often want a single laboratory to perform all of their testing services. In recent years, both governmental and private-sector payers have made efforts to contain or reduce healthcare costs, including for clinical laboratory services.

Reimbursement under the PFS is capped at different rates in each Medicare Administrative Contractor's jurisdiction. Pursuant to PAMA, unless modified by Congress, reimbursement under the CLFS is set at a national rate that is updated every three years for most tests. State Medicaid programs are prohibited from paying more than the Medicare fee schedule limit for clinical laboratory services furnished to Medicaid recipients. Laboratories primarily bill and are reimbursed by Medicare and Medicaid directly for covered tests performed on behalf of Medicare and Medicaid beneficiaries. For beneficiaries that participate in managed Medicare and managed Medicaid plans, laboratory bills are submitted to and paid by MCOs that manage those plans. Approximately 8.8% of Dx's revenue is reimbursed directly by Medicare under the CLFS.

Many pathology services performed by Dx are reimbursed by Medicare under the PFS. The PFS assigns relative value units to each procedure or service, and a conversion factor is applied to calculate the reimbursement. The PFS is also subject to adjustment on an annual basis. Such adjustments can impact both the conversion factor and relative value units. The Sustainable Growth Rate (SGR), the formula previously used to calculate the fee schedule conversion factor, would have resulted in significant decreases in payment for most physician services for each year since 2003. However, Congress intervened repeatedly to prevent these payment reductions, and the conversion factor was increased or frozen for the subsequent year. The Medicare Access and CHIP Reauthorization Act of 2015 (MACRA) permanently replaced the SGR formula and transitioned PFS reimbursement to a value-based payment system. MACRA retroactively avoided a 21.2% reduction in PFS reimbursement that had been scheduled for April 1, 2015, and provided for PFS conversion factor increases of 0.5% from July 1, 2015 to December 31, 2015, and 0.5% in each of years 2016-2019, followed by no updates for 2020 through 2025, and updates that vary based on participation in alternative payment models in subsequent years. These changes to the conversion factor may be offset by reductions to the relative value units, as was the case with the 2016 PFS reductions. For 2022, Congress increased the conversion factor by 3.0% over the amount announced in the final rule, instead of allowing a 3.75% reduction to take effect. In the Consolidated Appropriations Act of 2023, Congress mitigated PFS cuts in 2023 and 2024 by 2.5% and 1.25%, respectively, that would otherwise have been reduced by 4.47% in 2023 based on the conversion factor put forward in the 2023 Medicare PFS Final Rule. Approximately 0.4% of Dx's revenue is reimbursed under the PFS.

In addition to changes in reimbursement rates, Dx is also impacted by changes in coverage policies for laboratory tests and annual CPT coding revisions. Medicare, Medicaid and private payer diagnosis code requirements and payment policies negatively impact Dx's ability to be paid for some of the tests it performs. Further, some payers require additional information to process claims, employ third-party utilization management tools, or have implemented prior authorization policies which delay or prohibit payment.

Future changes in national, state, and local laws and regulations (or in the interpretation of current regulations) affecting government payment for clinical laboratory testing could have a material adverse effect on the Company.

Further healthcare reform could occur in 2024, including changes to the ACA and Medicare reform, as well as administrative requirements that may continue to affect coverage, reimbursement, and utilization of laboratory services in ways that are currently unpredictable.

Privacy, Security and Confidentiality of Health Information and Other Personal Information

In the U.S., the Health Insurance Portability and Accountability Act of 1996 (HIPAA) was designed to address issues related to the security and confidentiality of health information and to improve the efficiency and effectiveness of the healthcare system by facilitating the electronic exchange of information in certain financial and administrative transactions. These regulations apply to health plans and healthcare providers that conduct standard transactions electronically and healthcare clearinghouses (covered entities). Six such regulations include: (i) the Transactions and Code Sets Rule; (ii) the Privacy Rule; (iii) the Security Rule; (iv) the Standard Unique Employer Identifier Rule; (v) the National Provider Identifier Rule; and (vi) the Health Plan Identifier Rule. The Company, which may act as a HIPAA covered entity in certain circumstances, believes that it is in compliance in all material respects with each of the HIPAA Rules identified above.

The U.S. Health Information Technology for Economic and Clinical Health Act (HITECH), which was enacted in February 2009, with regulations effective on September 23, 2013, strengthened and expanded the HIPAA Privacy and Security Rules and their restrictions on use and disclosure of protected health information (PHI). HITECH includes, but is not limited to, prohibitions on exchanging PHI for remuneration and additional restrictions on the use of PHI for marketing. HITECH also imposes a number of Privacy Rule requirements and a majority of Security Rule provisions directly on business associates that were previously only directly applicable to covered entities. Moreover, HITECH requires covered entities to provide notice to individuals, HHS, and, as applicable, the media when unsecured PHI is breached, as that term is defined by HITECH. Business associates are similarly required to notify covered entities of a breach.

Index

The Privacy Rule regulates the use and disclosure of PHI by covered entities. It also sets forth certain rights that individuals have with respect to their PHI maintained by a covered entity, such as the right to access or amend certain records containing PHI or to request restrictions on the use or disclosure of PHI. The HIPAA Privacy Rule requires covered entities to contractually bind third parties, known as business associates, in the event that they perform an activity or service for or on behalf of the covered entity that involves the creation, receipt, maintenance, or transmission of PHI.

On February 6, 2014, CMS and HHS published final regulations that amended the HIPAA Privacy Rule to provide individuals (or their personal representatives) with the right to receive copies of their test reports from laboratories subject to HIPAA, or to request that copies of their test reports be transmitted to designated third parties.

On December 12, 2018, HHS issued a request for information (RFI) seeking input from the public on how the HIPAA regulations and the HIPAA Privacy Rule, in particular, could be modified to amend existing, or impose additional, obligations relating to the processing of PHI. Subsequent to the RFI, on January 21, 2021, HHS published a notice of proposed rulemaking (NPRM) containing potential modifications to the HIPAA Privacy Rule addressing standards that may impede the transition to value-based healthcare and strengthen individuals' rights to access their health information. The public comment period for the NPRM was closed on May 6, 2021. On April 12, 2023, HHS published a NPRM containing potential modifications to the HIPAA Privacy Rule addressing the use or disclosure of PHI in relation to the provision of reproductive health care pursuant to Executive Order 14076. The public comment period for the NPRM was closed on June 16, 2023. The Company is monitoring the NPRM process. If modifications to the HIPAA Privacy Rule are adopted, they may impact the Company's compliance obligations under HIPAA.

The administrative simplification provisions of HIPAA mandate the adoption of standard unique identifiers for healthcare providers. The intent of these provisions is to improve the efficiency and effectiveness of the electronic transmission of health information. The National Provider Identifier Rule requires that all HIPAA-covered healthcare providers, whether they are individuals or organizations, must obtain an NPI to identify themselves in standard HIPAA transactions. NPI replaces the unique provider identification number and other provider numbers previously assigned by payers and other entities for the purpose of identifying healthcare providers in standard electronic transactions.

Violations of the HIPAA provisions could result in civil and/or criminal penalties, including significant fines and up to 10 years in prison. HITECH also requires HHS to conduct periodic audits to confirm compliance and authorizes state attorneys general to bring civil actions seeking either injunctions or damages in response to violations of the HIPAA privacy and security regulations that affect the privacy of state residents.

The total cost associated with complying with the ongoing requirements of HIPAA and HITECH is not expected to be material to the Company’s operations or cash flows. However, future regulations and interpretations of HIPAA and HITECH could impose significant costs on the Company.

The information blocking provisions (Information Blocking Rules) of the 21st Century Cures Act became effective on April 5, 2021. The Information Blocking Rules prohibit covered actors, including healthcare providers, from engaging in activity that is likely to interfere with the access, exchanges, or use of electronic health information unless such activity falls into one of eight exceptions. The Information Blocking Rules provide for civil monetary penalties for noncompliance by healthcare information technology vendors and, separately, “appropriate disincentives” for noncompliance by healthcare providers. The Company believes that it is in compliance in all material respects with the requirements of the Information Blocking Rules.

In addition to the regulations described above, numerous other data protection, privacy and similar laws govern the confidentiality, security, use, and disclosure of personal information, as well as breach notification responsibilities. These laws vary by jurisdiction, but they most commonly regulate or restrict the collection, use, and disclosure of medical and financial information and other personal information. In the U.S., the Federal Trade Commission (FTC) has authority to regulate unfair or deceptive acts or practices, including with respect to data privacy and security. If the Company’s public statements about collection, use, or disclosure of personal information are perceived to be inconsistent with the Company’s actual practices, the Company may face accusations of unfairness or deception under the Federal Trade Commission Act of 1914 or state law equivalents. In addition, some state laws are more restrictive and, therefore, are not preempted by HIPAA. Penalties for violation of these laws may include sanctions against a laboratory's licensure, as well as civil and/or criminal penalties.

Effective August 14, 2020, the Substance Abuse and Mental Health Services Administration of HHS (SAMHSA) announced the finalization of proposed changes to the Confidentiality of Substance Use Disorder Patient Records regulation. This regulation protects the confidentiality of patient records relating to the identity, diagnosis, prognosis, or treatment that are maintained in connection with the performance of any federally assisted program or activity relating to substance use disorder education, prevention, training, treatment, rehabilitation, or research. Under the regulation, patient identifying information may only be released with the individual’s written consent, subject to certain limited exceptions. The latest changes to this regulation seek to better facilitate care coordination, while maintaining more stringent confidentiality of substance use disorder

information. The Company adopted changes to its policies and procedures necessary for compliance.

Congress and state legislatures also have been implementing new legislation relating to privacy and data protection. For example, on June 28, 2018, the California legislature passed the California Consumer Privacy Act (CCPA), which became effective January 1, 2020. The CCPA created transparency requirements and granted California residents several new rights with regard to their personal information. In addition, in November 2020, California voters approved the California Privacy Rights Act (CPRA) ballot initiative, which introduced significant amendments to the CCPA and established and funded a dedicated California privacy regulator, the California Privacy Protection Agency (CPPA). The amendments to the CCPA introduced by the CPRA went into effect on January 1, 2023, and new implementing regulations are expected to be introduced by the CPPA. Failure to comply with the CCPA may result in, among other things, significant civil penalties and injunctive relief, or potential statutory or actual damages. In addition, California residents have the right to bring a private right of action in connection with certain types of incidents. These claims may result in significant liability and potential damages. Other states have passed legislation similar to the CCPA, including Virginia, Colorado, Connecticut, Utah, Tennessee, Oregon, Montana, Iowa, Delaware, Texas and Indiana. These laws generally mirror the principles and requirements of the CCPA; however, these laws do not provide for a private right of action. Additionally, Washington and Nevada have passed legislation specific to consumer health data, both of which come into effect on March 31, 2024. The Company continues to assess the impact of these laws on the Company’s business, and the Company is implementing and will prepare to implement appropriate processes to manage compliance with these laws as they become effective and more guidance is provided.

The European Union General Data Protection Regulation (GDPR) became effective May 25, 2018, replacing Directive 95/46/EC. The GDPR established requirements applicable to the use and transfer of personal data and imposes penalties for noncompliance of up to the greater of €20 million or 4% of worldwide revenue. The GDPR, as well as the U.K.'s implementation -- the U.K. General Data Protection Regulation -- requires transparency with regard to the means and purposes of processing of personal data, collection of consent to process personal data in certain circumstances, the ability to provide records of processing upon request by a supervisory authority or data controller, implementation of appropriate technical and organizational measures to maintain security of personal data, notification of personal data breaches to supervisory authorities, data controllers, and individuals within expedient time frames, and performance of data protection impact assessments for certain processing activities. The GDPR also provides individual data subjects with certain rights, where applicable, including the right of access, the right to rectification, the right to be forgotten, the right to restrict or object to processing, and the right to data portability. The GDPR requires that personal data may only be transferred outside of the European Union to a country that offers an adequate level of data protection under standards set by the European Union, or where such transfer is otherwise pursuant to a legal framework approved by the European Union. On July 16, 2020, the Court of Justice of the European Union released its decision in Data Protection Commission v. Facebook Ireland Limited, Maximillian Schrems (Schrems II), which invalidated the EU-U.S. Privacy Shield as a legal framework for the transfer of personal data outside of the European Union, and suggesting additional safeguards for the use of Standard Contractual Clauses (SCCs) as a legal framework for the transfer of personal data outside of the European Union. On June 4, 2021, the European Commission release updated SCCs, which, in part, adopted many of the additional safeguards highlighted in the Schrems II decision. Companies using SCCs for the transfer of personal data outside of the European Union are required to use the new SCCs for new transfers of personal data as of September 27, 2021, and for all transfers of personal data as of December 27, 2022. The Company has established processes and frameworks to manage compliance with the GDPR and other global privacy and data protection requirements, and to manage preparation for future enacted regulations. Compliance could impose significant costs on the Company.

In addition to the GDPR, numerous other countries have laws governing the collection, use, disclosure, and transmission (including cross-border transfer) of personal information, including medical information. The legislative and regulatory landscape for privacy and data protection is complex and continually evolving. Data protection regulations have been enacted or updated in regions where the Company does business including in Asia and Europe, and in countries such as Canada, India, and the UK. Failure to comply with these regulations may result in, among other things, civil, criminal and contractual liability, fines, regulatory sanctions, and damage to the Company’s reputation.

Potential government regulation related to AI use and ethics may also increase compliance costs and impact operations as the Company continues to develop, test, adopt, and maintain AI within the Company's operations and in its products and services. The rapid evolution of AI, and potential government regulation, will require the application of resources to allow the Company to implement AI appropriately in order to minimize unintended, harmful impact, including from the exposure of Company or third-party information or the Company relying on flawed AI outputs. The Company has implemented an AI Code of Ethics and established an AI Ethics Board to review and help maintain compliance with AI ethical principles and regulatory requirements in the development and use of AI systems, including generative AI tools.

Fraud and Abuse Laws and Regulations

Existing U.S. laws governing federal healthcare programs, including Medicare and Medicaid, as well as similar state laws, impose a variety of broadly described fraud and abuse prohibitions on healthcare providers, including clinical laboratories.

Index

These laws are interpreted liberally and enforced aggressively by multiple government agencies, including the U.S. Department of Justice (DOJ), OIG and various state agencies. Historically, the clinical laboratory industry has been the focus of major governmental enforcement initiatives. The U.S. government's enforcement efforts have been conducted under statutory authorities such as those contained in HIPAA, which includes several provisions related to fraud and abuse enforcement, including the establishment of a program to coordinate and fund U.S., state and local law enforcement efforts, and in the Deficit Reduction Act of 2005, which included requirements directed at Medicaid fraud, including increased spending on enforcement and financial incentives for states to adopt false claims act provisions similar to the U.S. False Claims Act. Amendments to the False Claims Act, and other enhancements to the U.S. fraud and abuse laws enacted as part of the ACA, have further increased fraud and abuse enforcement efforts and compliance risks. For example, the ACA established an obligation to report and refund overpayments from Medicare or Medicaid within 60 days of identification (whether or not paid through any fault of the recipient); failure to comply with this requirement can give rise to additional liability under the False Claims Act and Civil Monetary Penalties statute.

The U.S. Anti-Kickback Statute prohibits knowingly providing anything of value in return for, or to induce the referral of, Medicare, Medicaid, or other U.S. federal healthcare program business. Violations can result in imprisonment, fines, penalties, and/or exclusion from participation in U.S. federal healthcare programs. The OIG has published “safe harbor” regulations that specify certain arrangements that are protected from prosecution under the Anti-Kickback Statute if all conditions of the relevant safe harbor are met. Failure to fit within a safe harbor does not necessarily constitute a violation of the Anti-Kickback Statute; rather, the arrangement would be subject to scrutiny by regulators and prosecutors and would be evaluated on a case-by-case basis. Many states have their own Medicaid anti-kickback laws, and several states also have anti-kickback laws that apply to all payers (i.e., not just government healthcare programs).

From time to time, the OIG issues alerts and other guidance on certain practices in the healthcare industry that implicate the Anti-Kickback Statute or other fraud and abuse laws. OIG Special Fraud Alerts and Advisory Opinions relevant to the Company set forth a number of practices allegedly engaged in by some clinical laboratories and healthcare providers that raise issues under the U.S. fraud and abuse laws, including the Anti-Kickback Statute. These practices include: (i) providing employees to furnish valuable services for physicians (other than collecting patient specimens for testing) that are typically the responsibility of the physicians’ staff; (ii) offering or providing discounted laboratory services billed to referral sources in return for referrals of other tests that are billed to U.S. federal healthcare programs; (iii) providing free testing to physicians’ managed care patients in situations where the referring physicians benefit from such reduced laboratory utilization; (iv) providing free pickup and disposal of biohazardous waste for physicians for items unrelated to a laboratory’s testing services; (v) providing general-use facsimile machines or computers to physicians that are not exclusively used in connection with the laboratory services; (vi) providing free testing for healthcare providers, their families and their employees (i.e., so-called “professional courtesy” testing); (vii) rental of space in physician offices by equipment suppliers or other healthcare entities to which the physicians make referrals; (viii) compensation paid by laboratories to physicians and hospitals for blood specimen processing and for submitting patient data to registries; (ix) remuneration provided to physicians and other health care professionals by pharmaceutical and medical device companies in connection with company-sponsored speaker programs; and (x) arrangements between telemedicine companies and healthcare professionals that result in the fraudulent ordering or prescribing of medically unnecessary services, including prescription drugs, durable medical equipment, and clinical laboratory testing.

In addition to the Anti-Kickback Statute, in October 2018, the U.S. enacted the Eliminating Kickbacks in Recovery Act of 2018 (EKRA), as part of the Substance Use-Disorder Prevention that Promotes Opioid Recovery and Treatment for Patients and Communities Act. EKRA is an all-payer anti-kickback law that makes it a criminal offense to pay any remuneration to induce referrals to, or in exchange for, patients using the services of a recovery home, a substance use clinical treatment facility, or laboratory. Although it appears that EKRA was intended to reach patient brokering and similar arrangements to induce patronage of substance use recovery and treatment, the language in EKRA is broadly written. As drafted, an EKRA prohibition on incentive compensation to sales employees is inconsistent with the federal anti-kickback statute and regulations, which permit payment of employee incentive compensation, a practice that is common in the industry. Significantly, EKRA permits the U.S. Department of Justice to issue regulations clarifying EKRA’s exceptions or adding additional exceptions, but such regulations have not yet been issued, and there is no additional DOJ or other government guidance to indicate how and to what extent it will be applied and enforced in the industry. The Company continues to work through its trade association to address the scope of EKRA.

Under another U.S. statute, known as the Stark Law or “physician self-referral” prohibition, physicians who have a financial or a compensation relationship with a clinical laboratory may not, unless an exception applies, refer Medicare or Medicaid patients for testing to the laboratory, regardless of the intent of the parties. Similarly, laboratories may not bill Medicare or Medicaid for services furnished pursuant to a prohibited self-referral. There are several Stark Law exceptions that are relevant to arrangements involving clinical laboratories, including: (i) fair market value compensation for the provision of items or services; (ii) payments by physicians to a laboratory for clinical laboratory services; (iii) ancillary services (including laboratory

Index

services) provided within the referring physician's own office, if certain criteria are satisfied; (iv) physician investment in a company whose stock is traded on a public exchange and has stockholder equity exceeding $75.0 million; and (v) certain space and equipment rental arrangements that are set at a fair market value rate and satisfy other requirements. Many states have their own self-referral laws as well, which in some cases apply to all patient referrals, not just government reimbursement programs.

In December 2020, the OIG and CMS published final rules to amend certain regulations implementing the Anti-Kickback Statute and the Stark Law, respectively. The amendments were primarily intended to alleviate perceived impediments to coordinated care and value-based compensation arrangements through new safe harbors to the Anti-Kickback Statute and new exceptions to the Stark Law, and have varying degrees of applicability to laboratories. The CMS final rule incorporates laboratories and permits support for value-based arrangements, under certain conditions for purposes of the Stark Law. However, the OIG final rule generally excludes laboratories from protection under the Anti-Kickback Statute safe harbors for value-based arrangements.

There are a variety of other types of U.S. and state fraud and abuse laws, including laws prohibiting submission of false or fraudulent claims and that require certain companies to disclose payments and other transfers of value to certain healthcare professionals and providers. The Company seeks to conduct its business in compliance with all U.S. and state fraud and abuse laws. The Company is unable to predict how these laws will be applied in the future, and no assurances can be given that its arrangements will not be subject to scrutiny under such laws. Sanctions for violations of these laws may include exclusion from participation in Medicare, Medicaid, and other U.S. or state healthcare programs, significant criminal and civil fines and penalties, and loss of licensure. Any exclusion from participation in a U.S. healthcare program, or material loss of licensure, arising from any action by any federal or state regulatory or enforcement authority, would likely have a material adverse effect on the Company's business. In addition, any significant criminal or civil penalty resulting from such proceedings could have a material adverse effect on the Company's business.

Enrollment and re-enrollment in U.S. healthcare programs, including Medicare and Medicaid, are subject to certain program integrity requirements intended to protect the programs from fraud, waste, and abuse. In September 2019, CMS published a final rule implementing program integrity enhancements to provider enrollment requiring Medicare, Medicaid, and Children’s Health Insurance Program (CHIP) providers and suppliers to disclose on an enrollment application or a revalidation application any current or previous direct or indirect affiliation with a provider or supplier that (i) has uncollected debt; (ii) has been or is subject to a payment suspension under a federal health care program; (iii) has been or is excluded by the OIG from Medicare, Medicaid, or CHIP, or (iv) has had its Medicare, Medicaid, or CHIP billing privileges denied or revoked. This rule permits CMS to deny enrollment based on such an affiliation when CMS determines that the affiliation poses an undue risk of fraud, waste, or abuse. CMS is phasing in this new affiliation disclosure requirement.

In November 2021, CMS published the 2022 Medicare PFS Final Rule, which included further program integrity requirements. CMS finalized its proposal to expand the categories of parties within the purview of the denial and revocation provisions to include excluded administrative or management services personnel who furnish services payable by a federal healthcare program, such as a billing specialist, accountant, or human resources specialist. CMS also codified the billing privilege deactivation rebuttal process, under which a provider or supplier would have 15 calendar days from receipt of written notice of a deactivation to submit a rebuttal, and CMS could, in its discretion, extend the 15-day period to account for certain special situations. In addition, CMS defined factors it would use to determine whether revocation or suspension of billing privileges is appropriate due to a pattern or practice of non-compliant billing, which would be: (i) the percentage of submitted claims that were denied during the period under consideration; (ii) whether the provider or supplier has any history of final adverse actions and the nature of any such actions; (iii) the type of billing non-compliance and the specific facts surrounding said non-compliance (to the extent this can be determined); and (iv) any other information regarding the provider's or supplier's specific circumstances that CMS deems relevant to the determination. This is a reduction in the number of factors that were previously considered and a revision of some previous factors.

Environment, Health, and Safety

The Company is subject to licensing and requirements under laws and regulations relating to the protection of the environment, and employee health and safety. These laws and regulations, designed to minimize risk to employee health and safety and to the environment, include the safe handling, use, transportation and disposal of potentially infectious and hazardous materials; the assessment of potential work-related risks and establishment of work practice and engineering controls, and providing protective clothing and equipment, training, and medical surveillance.

The Company is committed to reducing its carbon footprint. The Company participates in the Carbon Development Project and the EcoVadis sustainable procurement rating processes. In 2023, the Company's greenhouse gas emission reduction science-based targets were accepted by the Science Based Targets initiative (SBTi).

Index

Energy-saving measures at Company facilities include for example, installation of energy efficient boilers, chillers, ventilation systems, and LED lighting, engaging in waste-to-energy disposition, and reducing waste going to landfills. The Company is also committed to reducing the fuel use of its courier fleet, and in 2023 the Company added nearly 190 hybrid vehicles to its fleet, to help achieve its goals of reducing fuel use. Funding for these and similar projects continued through 2023 and is expected to continue through 2024.

The Company seeks to comply with all relevant environment, employee-health, and safety laws and regulations. Failure to comply could subject the Company to various administrative and/or other enforcement actions.

Drug Testing

Drug testing for public sector employees is regulated by the SAMHSA, which has established detailed performance and quality standards that laboratories must meet to be approved to perform drug testing on employees of U.S. government contractors and certain other entities. To the extent that the Company’s laboratories perform such testing, each must be certified as meeting SAMHSA standards. The Company’s laboratories in Research Triangle Park, North Carolina; Raritan, New Jersey; Houston, Texas; Southaven, Mississippi; St. Paul, Minnesota; and Portland, Oregon, are all SAMHSA certified. Each laboratory also maintains state licensure and laboratory certifications required to provide testing for private sector employers.

Controlled Substances

BLS handles controlled substances as part of the services it provides in preclinical testing. The use of controlled substances is regulated by the U.S. Drug Enforcement Administration under the Controlled Substances Act (CSA) and its implementing regulations. The CSA establishes, among other things, certain registration, security, recordkeeping, reporting, import, export, and other requirements for controlled substances. The Company seeks to conduct its business in compliance with these requirements as applicable. Violations of these rules may result in criminal and civil fines and penalties.

Compliance Program

The Company maintains a global compliance program that includes ongoing evaluation and monitoring of its compliance with the laws and regulations of the U.S. and the other countries in which it has operations. The objective of the Company’s compliance program is to develop, implement, monitor, and update compliance safeguards, as appropriate. Although the Company is subject to a broad range of regulations, its compliance program has a particular focus on regulations related to healthcare fraud and abuse, anti-kickback, physician self-referral, government reimbursement programs, anti-bribery/anti-corruption, anti-human trafficking, and trade sanctions, among others. Emphasis is placed on developing and implementing compliance policies and guidelines, personnel training programs, risk assessment, monitoring and auditing activities, and providing systems for reporting and investigation of potential or actual compliance concerns. The compliance program demonstrates the Company's commitment to conducting business at the highest standards of ethical conduct and integrity.

The Company seeks to conduct its business in compliance with all statutes, regulations, and other requirements applicable to its clinical laboratory operations and drug development business. The clinical laboratory industry and drug development industries are, however, subject to extensive regulation, and many of these statutes and regulations have not been interpreted by the courts. In addition, the applicability or interpretation of statutes and regulations may not be clear in light of emerging changes in clinical testing science, healthcare technology, and healthcare organizations. Applicable statutes and regulations may be interpreted or applied by a prosecutorial, regulatory, or judicial authority in a manner that would materially adversely affect the Company. Potential sanctions for violation of these statutes and regulations include significant civil and criminal penalties, fines, exclusion from participation in governmental healthcare programs, and the loss of various licenses, certificates, and authorizations necessary to operate, as well as potential liabilities from third-party claims, all of which could have a material adverse effect on the Company’s business.

Item 1A. RISK FACTORS

Investors should carefully consider all of the information set forth in this Annual Report, including the following risk factors, before deciding to invest in any of the Company’s securities. The risks below are not the only ones that the Company faces. Additional risks not presently known to the Company, or that it presently deems immaterial, may also negatively impact the Company. The Company’s business, consolidated financial condition, revenues, results of operations, profitability, reputation or cash flows could be materially impacted by any of these factors.

Risks Related to the Company's Business Including Global Economic and Sociopolitical Factors

General or macro-economic factors in the U.S. and globally may have a material adverse effect upon the Company, and significant fluctuations in global economic conditions and an increase in the costs of goods and services could negatively impact testing volumes, drug development services, cash collections, profitability, and the availability and cost of credit.

The Company’s operations are dependent upon ongoing demand for diagnostic testing and drug development services by

Index

patients, physicians, hospitals, MCOs, pharmaceutical, biotechnology and medical device companies and others. Fluctuations in global economic conditions, including inflation and the risk of short- or long-term recessions, could negatively impact demand for diagnostic testing and drug development services, the ability of customers to pay for the Company's services, and the Company’s profitability. In addition, uncertainty in the credit markets and interest rate volatility could reduce the availability and increase the cost of credit and impact the Company’s ability to meet its financing needs in the future.

Operations may be disrupted and adversely impacted by the effects of adverse weather, natural disasters, geopolitical events, public health crises, hostilities or acts of terrorism, acts of vandalism, disruption to supply chains, inaccessibility of natural resources, and other events beyond the Company's control.

Natural disasters, such as adverse weather, fires, earthquakes, power shortages and outages, geopolitical events, such as terrorism, war, political instability, or other conflict, public health crises and disease epidemics and pandemics, criminal activities, disruptions to supply chains, inaccessibility of natural resources, and other disruptions or events beyond the Company’s control could negatively affect the Company’s operations. Any of these events may result in a temporary decline of testing volumes and other work in both segments. In addition, such events may temporarily interrupt the Company’s ability to transport specimens, efficiently commence, continue, or complete its work on studies, utilize information technology systems, utilize certain laboratories, and/or to receive material from its suppliers. Such events can also affect customer operations and thereby impact testing volume. Long-term disruptions in the infrastructure and operations caused by such events (particularly involving locations in which the Company has operations), could harm the Company's operating results.

An inability to attract, retain, and develop experienced and qualified personnel, including key management personnel, and increased personnel costs, could adversely affect the Company’s business.

The loss of key management personnel or the inability to attract, retain, and develop experienced and qualified employees, at the Company’s clinical laboratories, drug development, and diagnostic facilities, and increased costs related to such personnel and employees, could adversely affect the business. The success of the Company is dependent in part on the efforts of key members of its management team. Success in maintaining the Company’s leadership position in genomic and other advanced testing and diagnostic technologies will depend in part on the Company’s ability to attract and retain skilled research professionals. In addition, the success of the Company’s early discovery, clinical, and commercial laboratories also depend on employing and retaining qualified and experienced professionals, including specialists, who perform laboratory research activities and testing services. The same is true for patient-facing staff with specialized training required to perform activities related to specimen collection or clinical research activities. In the future, if competition for the services of these professionals increases, the Company may not be able to continue to attract and retain individuals in its markets. Changes in key management, or the ability to attract, develop, and retain qualified personnel, as a result of increased competition for talent, wage growth, or other market factors, could lead to strategic and operational challenges and uncertainties, distractions of management from other key initiatives, and inefficiencies and increased costs, any of which could adversely affect the Company’s business, financial condition, results of operations, and cash flows.

Continued changes in healthcare reimbursement models and products (e.g., health insurance exchanges), changes in government payment and reimbursement systems, or changes in payer mix, including an increase in third-party benefits management and value-based payment models, could have a material adverse effect on the Company's revenues, profitability and cash flow.

Diagnostics Laboratories' (Dx) testing services are billed to MCOs, Medicare, Medicaid, physicians and physician groups, hospitals, patients, and employer groups. Most testing services are billed to a party other than the physician or other authorized person who ordered the test. Increases in the percentage of services billed to government and MCOs could have an adverse effect on the Company’s revenues.

The Company serves many MCOs. These organizations have different contracting philosophies, which are influenced by the design of their products. Some MCOs contract with a limited number of clinical laboratories and engage in direct negotiation of rates. Other MCOs adopt broader networks with generally uniform fee structures for participating clinical laboratories. In some cases, those fee structures are specific to independent clinical laboratories, while the fees paid to hospital-based and physician-office laboratories may be different, and are typically higher. MCOs may also offer Managed Medicare or Managed Medicaid plans. In addition, an increasing number of MCOs are implementing, directly or through third parties, various types of laboratory benefit management programs that may include laboratory networks, utilization management tools (such as prior authorization and/or prior notification), and claims edits, which may impact coverage or reimbursement for commercial laboratory tests. Some of these programs address commercial laboratory testing broadly, while others are focused on certain types of testing such as molecular, genetic and toxicology testing. An increase in the use of such programs could lead to increased denial of claims, extended appeals, and reduced revenue.

Index

Some MCOs use capitation rates to fix the cost of laboratory testing services for their enrollees. Under a capitated reimbursement arrangement, the clinical laboratory receives a per-member, per-month payment for an agreed upon menu of laboratory tests provided to MCO members during the month, regardless of the number of tests performed. Capitation shifts the risk of increased test utilization (and the underlying mix of testing services) to the commercial laboratory provider. The Company makes significant efforts to obtain adequate compensation for its services in its capitated arrangements. For the year ended December 31, 2023, such capitated contracts accounted for approximately $369.9 million, or 3.9%, of Dx's revenues.

The Company's ability to attract and retain MCOs is critical given the impact of healthcare reform, related products and expanded coverage (e.g. health insurance exchanges and Medicaid expansion) and evolving value-based care and risk-based reimbursement delivery models (e.g., accountable care organizations (ACOs) and Independent Physician Associations (IPAs)).

A portion of the managed care fee-for-service revenues is collectible from patients in the form of deductibles, coinsurance and copayments. As patient cost-sharing has been increasing, the Company's collections may be adversely impacted.

In addition, Medicare and Medicaid and private insurers have increased their efforts to control the cost, utilization and delivery of healthcare services, including commercial laboratory services. Measures to regulate healthcare delivery in general, and clinical laboratories in particular, have resulted in reduced prices, added costs and decreased test utilization for the commercial laboratory industry by increasing complexity and adding new regulatory and administrative requirements. Pursuant to legislation passed in late 2003, the percentage of Medicare beneficiaries enrolled in Managed Medicare plans has increased. The percentage of Medicaid beneficiaries enrolled in Managed Medicaid plans has also increased; however, changes to, or repeal of, the Patient Protection and Affordable Care Act (ACA) may continue to affect coverage, reimbursement, and utilization of laboratory services, as well as administrative requirements, in ways that are currently unpredictable. Further healthcare reform could adversely affect laboratory reimbursement from Medicare, Medicaid or commercial carriers.

The Company has periodically experienced delays in the pricing and implementation of coding and billing changes among various payers, including Medicaid, Medicare and commercial carriers. Payer policy changes in coverage, along with coding and billing changes, have had a negative impact over time on revenue, revenue per requisition, and margins and cash flows. In 2023, limited coding and billing changes were implemented. While limited changes are expected to be implemented in 2024, the Company typically expects some delays in pricing and reimbursement as new codes are introduced.

The Company expects the efforts to impose reduced reimbursement, more stringent payment policies, and utilization and cost controls by government and other payers to continue. If Dx cannot offset additional reductions in the payments it receives for its services by reducing costs, increasing test volume, and/or introducing new services and procedures, it could have a material adverse effect on the Company’s revenues, profitability and cash flows. In 2014, Congress passed PAMA, requiring Medicare to change the way payment rates are calculated for tests paid under the CLFS, and to base the payment on the weighted median of rates paid by private payers. On June 23, 2016, CMS issued a final rule to implement PAMA that required applicable laboratories, including Dx, to begin reporting their test-specific private payer payment amounts to CMS in 2017, based on data collected in 2016. CMS used that private market data to calculate weighted median prices for each test (based on applicable current procedural technology (CPT) codes) to represent the new CLFS rates beginning in 2018, subject to certain phase-in limits. For 2018-2020, a test price could not be reduced by more than 10% per year. As a result of provisions included within the CARES Act, PAMA rate reductions for 2021 were suspended, and therefore the Company did not experience any incremental reimbursement rate impact due to PAMA in 2021. As a result of the Protecting Medicare and American Farmers from Sequester Cuts Act that became law in December 2021, the data reporting requirements and Medicare reimbursement cuts that would have occurred under PAMA in 2022 were delayed by one additional year, and the Company did not experience incremental reimbursement rate impact due to PAMA in 2022. As a result of the Consolidated Appropriations Act, 2023, which became law in December 2022, the data reporting requirements and Medicare reimbursement cuts that would have occurred under PAMA in 2023 were delayed by one additional year, and the Company did not experience an incremental reimbursement rate impact due to PAMA in 2023. In November 2023, provisions in the Further Continuing Appropriations and Other Extensions Act of 2024 further delayed data reporting requirements and the phase-in of payment reductions for Clinical Diagnostic Laboratory Tests (CDLTs) that are not classified as ADLTs under PAMA. As a result, no payment reduction will be applied to CDLTs in 2024, and for 2025-2027 payment may not be reduced by more than 15% compared to the payment amount established for a test the previous year.

CLFS rates for 2028 and subsequent periods will not be subject to phase-in limits. The phase-in of rates for CDLTs established in 2018 will resume in 2025. New CLFS rates will be established in 2026 based on data from 2019 to be reported in 2025. The process of data reporting and repricing under PAMA will be repeated every three years for CDLTs beginning in 2025. CLFS rates for ADLTs will be updated annually.

CMS published its initial proposed CLFS rates under PAMA for 2018-2020 on September 22, 2017. Following a public comment period, CMS made adjustments and published final CLFS rates for 2018-2020 on November 17, 2017, with additional adjustments published on December 1, 2017. For 2020, the Company realized a net reduction in reimbursement of

Index

approximately $72.0 million from all payers affected by the CLFS (approximately $107.0 million in 2019). PAMA rates were frozen for years 2021 through 2024 as described above. Unless implementation of PAMA is further delayed or changed, an additional reduction of approximately $100.0 million is expected for 2025, from all payers affected by the CLFS.

Changes in government regulation or in practices relating to the pharmaceutical, biotechnology, or medical device industries could decrease the need for certain services that BLS provides.

BLS assists pharmaceutical, biotechnology, and medical device companies in navigating the regulatory approval process. Changes in government regulations, such as a relaxation in regulatory requirements or the introduction of simplified approval procedures or an increase in regulatory requirements that BLS may have difficulty satisfying or that may make its services less competitive, could eliminate or substantially reduce the demand for its services. Also, if government efforts to contain drug and medical product and device costs impact profits from such items, or if health insurers were to change their practices with respect to reimbursement for those items, some of BLS’s customers may spend less, or reduce their growth in spending on R&D.

In addition, proposed changes in the U.S. relating to FDA oversight of the development and commercialization of LDTs as medical devices pursuant to regulatory interpretation, as well as draft legislation, if implemented, could increase costs, penalties, or fines. Any such new laws or regulations may create a risk of liability, increase BLS costs and/or limit service offerings through BLS.

Increased competition, including price competition, could have an adverse effect on the Company’s revenues and profitability.

As further described in Item 1 of Part I of this Annual Report, both Dx and BLS operate in competitive industries. The commercial laboratory business is intensely competitive both in terms of price and service. Pricing of laboratory testing services is often one of the most significant factors used by physicians, third-party payers and consumers in selecting a laboratory. As a result of significant consolidation in the commercial laboratory industry, larger commercial laboratory providers are able to increase cost efficiencies afforded by large-scale automated testing. This consolidation results in greater price competition. Dx may be unable to increase cost efficiencies sufficiently, if at all, and as a result, its net earnings and cash flows could be negatively impacted by such price competition. The Company may face increased competition from health system laboratories, due to physicians within those systems directing their testing to the health system laboratory and away from the Company, and as those laboratories seek to expand their testing volume from unaffiliated physicians in their service areas. The Company may also face competition from companies that do not comply with existing laws or regulations or otherwise disregard compliance standards in the industry. Additionally, the Company may also face changes in fee schedules, competitive bidding for laboratory services, or other actions or pressures reducing payment schedules as a result of increased or additional competition.

Following the spin-off of Fortrea, BLS’s main competition ranges from hundreds of small providers to a limited number of large companies with global capabilities. BLS competes against these small and large businesses, as well as in-house departments of pharmaceutical, biotechnology, medical device, and diagnostic companies, and to a lesser extent, selected academic research centers, universities, and teaching hospitals. In addition, BLS’s services periodically experience periods of increased price competition that may have an adverse effect on the segment’s profitability and consolidated revenues and net income.

Failure to obtain and retain new customers, the loss of existing customers or material contracts, or a reduction in services or tests ordered or specimens submitted by existing customers, or the inability to retain existing and/or create new relationships with health systems could impact the Company’s ability to successfully grow its business.

To maintain and grow its business, the Company needs to obtain and retain new customers and business partners. In addition, a reduction in tests ordered or specimens submitted by existing customers, a decrease in demand for the Company's services from existing customers, or the loss of existing contracts, without offsetting growth in its customer base, could impact the Company's ability to successfully grow its business and could have a material adverse effect on the Company’s revenues and profitability. The Company competes primarily on the basis of reputation, efficient and timely performance, and leadership in science, technology and innovation. The Company's failure to successfully compete in any of these areas could result in the loss of existing customers, an inability to gain new customers, and reduced or stagnant growth of the Company's business.

Discontinuation or recalls of existing testing products; failure to develop or acquire licenses for new or improved testing technologies; or the Company’s customers using new technologies to perform their own tests could adversely affect the Company’s business.

From time to time, manufacturers discontinue or recall reagents, test kits, or instruments used by the Company to perform laboratory testing. Such discontinuations or recalls could adversely affect the Company’s costs, testing volume and revenue.

Index

The commercial laboratory industry is subject to changing technology and new product introductions. The Company’s success in maintaining a leadership position in genomic and other advanced testing technologies will depend, in part, on its ability to develop, acquire or license new and improved technologies on favorable terms and to obtain appropriate coverage and reimbursement for these technologies. The Company may not be able to negotiate acceptable licensing arrangements, and it cannot be certain that such arrangements will yield commercially successful diagnostic tests. If the Company is unable to license these testing methods at competitive rates, its R&D costs may increase as a result. In addition, if the Company is unable to license new or improved technologies to expand its esoteric testing operations, its testing methods may become outdated when compared with the Company’s competition, and testing volume and revenue may be materially and adversely affected.

In addition, advances in technology may lead to the development of more cost-effective technologies, such as point-of-care testing equipment that can be operated by physicians or other healthcare providers (including physician assistants, nurse practitioners, and certified nurse midwives, generally referred to herein as physicians) in their offices or by patients themselves without requiring the services of freestanding clinical laboratories. Development of such technology and its use by the Company’s customers could reduce the demand for its laboratory testing services and the utilization of certain tests offered by the Company and negatively impact its revenues. Similarly, application of artificial intelligence to testing could reduce demand for the Company's services, or competitors could adopt use of these technologies and derive benefits from them sooner than the Company.

Currently, most commercial laboratory testing is categorized as high or moderate complexity, and thereby is subject to extensive and costly regulation under CLIA. The cost of compliance with CLIA makes it impractical for most physicians to operate clinical laboratories in their offices, and other laws limit the ability of physicians to have ownership in a laboratory and to refer tests to such a laboratory. Manufacturers of laboratory equipment and test kits could seek to increase their sales by marketing point-of-care laboratory equipment to physicians and by selling test kits approved for home or physician office use to both physicians and patients. Diagnostic tests approved for home use are automatically deemed to be “waived” tests under CLIA and may be performed in physician office laboratories as well as by patients in their homes with minimal regulatory oversight. Other tests meeting certain FDA criteria also may be classified as “waived” for CLIA purposes. The FDA has regulatory responsibility over instruments, test kits, reagents and other devices used by clinical laboratories, and it has responsibility for classifying the complexity of tests for CLIA purposes. Increased approval of “waived” test kits could lead to increased testing by physicians in their offices or by patients at home, which could affect the Company’s market for laboratory testing services and negatively impact its revenues.

Changes or disruption in services, supplies, or transportation provided by third parties have impacted and could continue to impact or adversely affect the Company’s business.

The Company depends on third parties to provide supplies and services critical to the Company’s business. Although the Company has a significant proprietary network of ground and air transport capabilities, certain of the Company's businesses are heavily reliant on third-party ground and air travel for transport of clinical trial and diagnostic testing supplies and specimens, research products, and people. A significant disruption to these travel systems, or the Company's access to them, could have a material adverse effect on the Company's business. The Company is also reliant on an extensive network of third-party suppliers and vendors of certain services and products, including for certain animal populations. Disruptions to the continued supply, or increases in costs, of these services, products, or animal populations may arise from export/import restrictions or embargoes, political or economic instability, pressure from animal rights activists, adverse weather, natural disasters, public health crises, transportation disruptions, cybersecurity incidents, or other causes, as well as from termination of relationships with suppliers or vendors for their failure to follow the Company’s performance standards and requirements. Disruption of supply and services has impacted and could continue to impact or have a material adverse effect on the Company’s business.

A failure to identify and successfully close and integrate strategic acquisition targets could have a material adverse effect on the Company's business objectives and its revenues and profitability.

Part of the Company's strategy involves deploying capital in investments that enhance the Company's business, which includes pursuing strategic acquisitions to strengthen the Company's scientific capabilities and enhance therapeutic expertise, enhance esoteric testing and global drug development capabilities, and increase presence in key geographic areas. Since 2019, the Company has invested net cash of approximately $3.5 billion in strategic business acquisitions. However, the Company cannot assure that it will be able to identify acquisition targets that are attractive to the Company or that are of a large enough size to have a meaningful impact on the Company's operating results. Furthermore, the successful closing and integration of a strategic acquisition entails numerous risks, including, among others:

•failure to obtain regulatory clearance, including due to antitrust concerns;

•loss of key customers or employees as a result of the acquisition;

•difficulty in consolidating redundant facilities and infrastructure and in standardizing information and other systems;

•unidentified regulatory problems at the acquired company or business;

Index

•failure to maintain the quality of services that such companies or businesses have historically provided;

•unanticipated costs and other liabilities;

•potential liabilities related to litigation related to the acquired company or business, or from its prior owners;

•failure to timely identify and remediate noncompliant activities of the acquired company or business;

•potential periodic impairment of goodwill and intangible assets acquired;

•coordination of geographically separated facilities and workforces; and

•the potential disruption of the Company's ongoing business and diversion of management's resources.

The Company cannot assure that current or future acquisitions, if any, or any related integration efforts will be successful, or that the Company's business will not be adversely affected by any future acquisitions, including with respect to revenues and profitability. Even if the Company is able to successfully integrate the operations of companies and businesses that it acquires in the future, the Company may not be able to realize the benefits that it expects from such acquisitions.

Unfavorable labor environments, union strikes, work stoppages, union or works council negotiations, or failure to comply with labor or employment laws could adversely affect the Company's operations and have a material adverse effect upon the Company's business.

The Company is a party to a limited number of collective bargaining agreements with various labor unions and is subject to employment and labor laws and unionization activity in the U.S. Similar employment and labor obligations exist across other countries in which it conducts business, including appropriate engagement with works councils in Europe. Disputes with regard to the terms of labor agreements or obligations for consultation, potential inability to negotiate acceptable contracts with these unions, unionization activity, or a failure to comply with labor or employment laws could result in, among other things, labor unrest, strikes, work stoppages, slowdowns by the affected workers, fines and penalties. If any of these events were to occur, or other employees were to become unionized, the Company could experience a significant disruption of its operations or higher ongoing labor costs, either of which could have a material adverse effect upon the Company's business. Additionally, future labor agreements, or renegotiation of labor agreements or provisions of labor agreements, or changes in labor or employment laws, could compromise its service reliability and significantly increase its costs, which could have a material adverse effect upon the Company's business. Also, the Company may incur substantial additional costs and become subject to litigation and enforcement actions if the Company fails to comply with legal requirements affecting its workforce and labor practices, including laws and regulations related to wage and hour practices, Office of Federal Contract Compliance Programs compliance, and unlawful workplace harassment and discrimination.

Continued and increased consolidation of pharmaceutical, biotechnology and medical device companies, health systems, physicians and other customers could adversely affect the Company's business.

Many healthcare companies and providers, including pharmaceutical, biotechnology and medical device companies, health systems, and physician practices are consolidating through mergers, acquisitions, joint ventures, and other types of transactions and collaborations. In addition to these more traditional horizontal mergers that involve entities that previously competed against each other, the healthcare industry is experiencing an increase in vertical mergers, which involve entities that previously did not offer competing goods or services. As the healthcare industry consolidates, competition to provide goods and services may become more intense, and vertical mergers may give those combined companies greater control over more aspects of healthcare, including increased bargaining power. This competition and increased customer bargaining power may adversely affect the price and volume of the Company’s services.

In addition, as the broader healthcare industry trend of consolidation continues, including the acquisition of physician practices by health systems, relationships with hospital-based health systems and integrated delivery networks are becoming increasingly important. Dx has a well-established base of relationships with those systems and networks, including collaborative agreements. Dx's inability to retain its existing relationships with those physicians as they become part of healthcare systems and networks and/or to create new relationships could impact its ability to successfully grow its business.

Damage or disruption to the Company’s facilities or operations therein could adversely affect the Company’s business.

Many of the Company’s facilities or the operations conducted therein could be difficult to replace in a short period of time. Any event that causes a disruption of the operation of these facilities might impact the Company's ability to provide services to customers and, therefore, could have a material adverse effect on the Company's financial condition, results of operations, and cash flows.

The failure to establish, update, or perform to appropriate quality standards could adversely affect the Company’s business and reputation.

The Company has quality control systems and processes to support the performance and delivery of its services. A failure to establish, update, or perform in accordance with those systems or processes could adversely affect the Company’s business

Index

operations, resulting in the loss of customers, loss or suspension of licensure or certifications, imposition of sanctions or other penalties, damage to the Company’s reputation, or other adverse effects.

Risks Related to Financial Matters

The Company bears financial risk for contracts that, including for reasons beyond the Company's control, may be underpriced, subject to cost overruns, delayed, or terminated or reduced in scope.

The Company has many contracts that are structured as fixed-price for fixed-contracted services or fee-for-service with a cap. The Company bears the financial risk if these contracts are underpriced or if contract costs exceed estimates. Such underpricing or significant cost overruns could have an adverse effect on the Company's business, results of operations, financial condition, and cash flows.

Many of BLS’s contracts, in particular, provide for services on a fixed-price or fee-for-service with a cap basis and they may be terminated or reduced in scope either immediately or upon notice. Cancellations may occur for a variety of reasons, including:

•failure of products to satisfy safety requirements;

•unexpected or undesired results of the products;

•insufficient clinical trial subject enrollment;

•insufficient investigator recruitment;

•a customer's decision to terminate the development of a product or to end a particular study; and

•BLS’s failure to perform its duties properly under the contract.

Although BLS' contracts often entitle the Company to receive the costs of winding down the terminated projects, as well as all fees earned up to the time of termination, the loss, reduction in scope or delay of a large contract or the loss, delay or conclusion of multiple contracts could materially adversely affect BLS.

A significant increase in the Company's days sales outstanding could have an adverse effect on the Company’s business, including its cash flow, by increasing its bad debt or decreasing its cash flow.

Billing for laboratory services is a complex process. Laboratories bill many different payers, including doctors, patients, hundreds of insurance companies, Medicare, Medicaid, and employer groups, all of which have different billing requirements. In addition to billing complexities, Dx has experienced an increase in patient responsibility as a result of managed care fee-for-service plans that continue to increase patient deductibles, coinsurance and copayments, or implement restrictive coverage or administrative policies that can further increase patient costs. Dx expects this trend to continue. A material increase in Dx’s days sales outstanding level could have an adverse effect on the Company's business, including potentially increasing its bad debt rate and decreasing its cash flows. Although BLS does not face the same level of complexity in its billing processes, it could also experience delays in billing or collection, and a material increase in BLS’s days sales outstanding could have an adverse effect on the Company’s business, including potentially decreasing its cash flows.

BLS’s revenues depend on the pharmaceutical, biotechnology and medical device industries.

BLS’s revenues depend greatly on the expenditures made by the pharmaceutical, biotechnology and medical device industries in R&D. In some instances, these companies are reliant on their ability to raise capital in order to fund their R&D projects. These companies are also reliant on reimbursement for their products from government programs and commercial payers. Accordingly, economic factors and industry trends affecting BLS’s customers in these industries may also affect BLS. If these companies were to reduce the number of R&D projects they conduct or outsource, whether through the inability to raise capital, reductions in reimbursement from governmental programs or commercial payers, industry trends, economic conditions or otherwise, BLS could be materially adversely affected.

Foreign currency exchange fluctuations could have an adverse effect on the Company’s business.

The Company has business and operations outside the U.S., and BLS derives a significant portion of its revenues from international operations. Since the Company's consolidated financial statements are denominated in U.S. dollars, fluctuations in exchange rates from period to period will have an impact on reported results. In addition, BLS may incur costs in one currency related to its services or products for which it is paid in a different currency. As a result, factors associated with international operations, including changes in foreign currency exchange rates, could significantly affect BLS's results of operations, financial condition and cash flows.

The Company’s uses of financial instruments to limit its exposure to interest rate and currency exchange fluctuations could expose it to risks and financial losses that may adversely affect the Company’s financial condition, liquidity and results of operations.

Index

To limit the Company’s exposure to interest rate fluctuations and currency exchange fluctuations, it has entered into, and in the future may enter into for these or other purposes, financial swaps, or hedging arrangements, with various financial counterparties. In addition to any risks related to the counterparties, there can be no assurances that the Company’s hedging activity will be effective in insulating it from the risks associated with the underlying transactions, that the Company would not have been better off without entering into these hedges, or that the Company will not have to pay additional amounts upon settlement.

The Company’s level of indebtedness and debt service requirements could adversely affect the Company’s liquidity, results of operations and business.

At December 31, 2023, indebtedness on the Company's outstanding Senior Notes totaled approximately $4.2 billion in aggregate principal, of which $1.0 billion is payable within the next 12 months. The Company is also a party to credit agreements relating to a $1.0 billion revolving credit facility. Under the revolving credit facility, the Company is subject to negative covenants limiting subsidiary indebtedness and certain other covenants typical for investment-grade-rated borrowers, and the Company is required to maintain a leverage ratio within certain limits.

The Company’s level of indebtedness and debt service requirements could adversely affect its business. In particular, it could increase the Company’s vulnerability to sustained, adverse macroeconomic weakness, limit its ability to obtain further financing or refinance existing debt at maturity, and limit its ability to pursue certain operational and strategic opportunities, including large acquisitions. Additionally, the Company's cost of funds could increase due to the impact of increases in prevailing interest rates on its variable rate debt and should the Company refinance existing debt at maturity or obtain further financing.

The Company may also enter into additional transactions or credit facilities, including other long-term debt, which may increase its indebtedness and result in additional restrictions upon the business. In addition, major debt rating agencies regularly evaluate the Company's debt based on a number of factors. There can be no assurance that the Company will be able to maintain its existing debt ratings, and failure to do so could adversely affect the Company's cost of funds, liquidity and access to capital markets.

The Company's quarterly operating results may vary.

The Company's operating results may vary significantly from quarter to quarter and are influenced by factors over which the Company has little control, such as:

•changes in the global economy;

•currency exchange rate fluctuations;

•the commencement, completion, delay or cancellation of large projects or contracts or groups of projects;

•the progress of ongoing projects;

•adverse weather, natural disasters, geopolitical events, public health crises, hostilities or acts of terrorism, acts of vandalism, disruption to supply chains, inaccessibility of natural resources, and other events beyond the Company’s control;

•the timing of and costs associated with completed acquisitions or other events; and

•changes in the utilization mix of the Company's services.

The Company believes that operating results for any particular quarter are not necessarily a meaningful indication of future results. While fluctuations in the Company's quarterly operating results could negatively or positively affect the market price of the Company's common stock, these fluctuations may not be related to the Company's future overall operating performance.

The Company depends on a variety of U.S. and international financial institutions to provide us with banking services. The default or failure of one or more of the financial institutions that the Company relies on may adversely affect the Company's business and financial condition.

The Company maintains the majority of its cash and cash equivalents in accounts with major U.S. and international financial institutions, and its deposits at certain of these institutions exceed insured limits. Market conditions can impact the viability of these institutions. In the event of failure of any of the financial institutions where the Company maintains its cash and cash equivalents, there can be no assurance that the Company would be able to access uninsured funds in a timely manner or at all. Additionally, bank payment processes could become unavailable which could temporarily impact the Company's ability to conduct business with suppliers and pay its employees on a timely basis. Any inability to access or delay in accessing these funds could adversely affect the Company's business and financial condition.

The Company might not be able to engage in certain desirable capital-raising or strategic transactions.

The Company’s ability to engage in certain transactions could be limited or restricted in order to preserve, for U.S. federal income tax purposes, the tax-free qualification of the Fortrea spin-off and certain related transactions under Sections 355 and

Index

368(a)(1)(D) of the Internal Revenue Code. Even if the spin-off and certain related transactions otherwise qualify for tax-free treatment under Section 355 of the Code, they may result in corporate-level taxable gain to the Company if there is a 50% or greater change in ownership, by vote or value, of shares of the Company’s stock, Fortrea’s stock, or the stock of a successor of either occurring as part of a plan or series of related transactions that includes the spin-off, which is generally presumed to include any acquisitions or issuances of stock within two years of the spin-off. To avoid realizing such taxable gain, the Company may be restricted or limited in its capital-raising or in the strategic transactions that it elects to pursue during such time period.

The recently completed spin-off of Fortrea may not achieve the intended results.

On June 30, 2023, the Company completed the previously announced spin-off of Fortrea Holdings Inc. (Fortrea). The spin-off poses risks and challenges that could impact the Company’s business, including, but not limited to, the failure to achieve the intended benefits from the spin-off, the failure to receive tax- free treatment for U.S. federal income purposes, and potential exposure to unexpected claims, liabilities, or costs under the Company’s agreements with Fortrea in connection with the spin-off.

The spin-off may adversely impact relationships with customers, suppliers, employees, and other business counterparties and the Company may experience delays, business disruption, increased costs, including from lost synergies, which could adversely affect the Company’s business, financial condition, and results of operations. The Company may also experience increased challenges in attracting, retaining, and motivating key personnel, which could harm the Company’s business. The Company's ongoing transitional and commercial arrangements with Fortrea intend to provide for a seamless delivery of services to the customers and other stakeholders of the independent companies following the spin-off, but those arrangements may not meet the intended objectives and could have unexpected costs or challenges, which could negatively impact the Company’s business, including relationships with customers and other business counterparties, and which could also result in a decline in value of the Company.

Risks Related to Technology and Cybersecurity

Failure to maintain the security of customer-related information or compliance with security requirements could damage the Company’s reputation with customers, cause it to incur substantial additional costs and become subject to litigation and enforcement actions.

The Company receives and stores certain personal and financial information about its customers. In addition, the Company depends upon the secure transmission of confidential information over public networks, including information permitting cashless payments. The Company also works with third-party service providers and vendors that provide technology systems and services that are used in connection with the receipt, storage, and transmission of customer personal and financial information. A compromise in the Company’s security systems, or those of the Company's third-party service providers and vendors, that results in customer personal information being obtained by unauthorized persons, or the Company’s or a third party's failure to comply with security requirements for financial transactions, including security standards for payment cards (e.g., the Payment Card Industry Data Security Standard), could adversely affect the Company’s reputation with its customers and others, as well as the Company’s results of operations, financial condition and liquidity. It could also result in litigation against the Company and the imposition of fines and penalties. For example, in connection with the AMCA Incident (as defined below under “Cybersecurity” in Item 1C) the Company has incurred, and expects to continue to incur, costs, and the Company is involved in pending and threatened litigation, as well as various government and regulatory inquiries and processes. For additional information about the AMCA Incident, see Note 15 Commitments and Contingencies to the Consolidated Financial Statements of Part III of the Annual Report.

Failure in the Company’s information technology systems or delays or failures in the development and implementation of new systems or updates or enhancements to existing systems could disrupt the Company’s operations or customer relationships.

The Company’s operations and customer relationships depend, in part, on the continued performance of its information technology systems. A failure of the network or data-gathering procedures could impede the processing of data, delivery of databases and services, customer orders and day-to-day management of the business and could result in the corruption or loss of data. Despite network security measures and other precautions the Company has taken, including the development of disaster recovery plans, its information technology systems are potentially vulnerable to physical or electronic break-ins, computer viruses, fire, natural disaster, power loss, telecommunications failures, cybersecurity incidents and similar disruptions, and there may not be adequate protections, mitigation plans or redundant facilities available in the event of such system failures. In addition, the Company may experience system failures or interruptions as it integrates the information technology systems of newly acquired businesses. Failures or interruption of the Company’s systems in one or more of its operations could result in interruptions of service, disrupt the Company’s ability to process laboratory requisitions, perform testing, provide test results or drug development data in a timely manner and/or conduct timely billing operations. Such system failures could require the

Index

Company to transfer operations to an alternative provider of services, which could result in delays in the delivery of products and services to customers. Additionally, significant delays in the planned delivery of system enhancements or improvements, or inadequate performance of the systems once they are complete could damage the Company's reputation and harm the business. Furthermore, failure of the Company’s information technology systems could adversely affect the Company’s business, profitability, financial condition, and reputation.

Cybersecurity incidents and unauthorized access to the Company's or its customers’ data could harm the Company’s reputation and adversely affect its business.

The Company has experienced and expects to continue to experience attempts by computer programmers and hackers to penetrate the Company’s layered cybersecurity controls, like the 2018 ransomware attack. The Company has also experienced and expects to continue to experience similar attempts to penetrate the systems of third-party suppliers and vendors to whom the Company has provided data, like the 2019 AMCA data breach. These attempts, if successful, could result in the misappropriation or compromise of personal information or proprietary or confidential information stored within the Company's systems or within the systems of third parties, create system disruptions or cause shutdowns. External actors are developing and deploying viruses, worms and other malicious software programs that attack the Company’s systems, the systems of third-parties, or otherwise exploit any security vulnerabilities. Outside parties may also attempt to fraudulently induce employees to take actions, including the release of confidential or sensitive information or to make fraudulent payments through illegal electronic spamming, phishing, spear phishing, or other tactics.

The Company has robust information security procedures and other safeguards in place, including evaluating the cybersecurity status of third-party suppliers and vendors that will have access to the Company’s data or information technology systems, which are monitored and routinely tested internally and by external parties. However, because the techniques used to obtain unauthorized access, disable or degrade service, or sabotage systems change frequently and often are not recognized until launched against a target, the Company may be unable to anticipate all of these techniques or to implement adequate preventive measures. In addition, as cyber threats continue to evolve, the Company may be required to expend additional resources to continue to enhance the Company’s information security measures or to investigate and remediate any information security vulnerabilities. The Company’s remediation efforts may not be successful and could result in interruptions, delays or cessation of service. This could also impact the cost and availability of cyber insurance to the Company. Cybersecurity incidents affecting the Company’s or third parties' security measures and the unauthorized dissemination of personal, proprietary or confidential information about the Company or its customers or other third parties could expose customers’ private information. Such incidents could expose customers to the risk of financial or medical identity theft or expose the Company or other third parties to a risk of loss or misuse of this information, result in litigation and potential liability for the Company, damage the Company’s brand and reputation or otherwise harm the Company’s business. Any of these disruptions or incidents could have a material adverse effect on the Company’s business, regulatory compliance, financial condition and results of operations.

In addition, the Company faces increased cybersecurity risks due to the number of employees that continue to work remotely, which remains at levels higher than prior to the COVID-19 pandemic as a result of changes in the workplace and to management and employee expectations. Increased levels of remote access create additional opportunities for cybercriminals to exploit vulnerabilities, and employees may be more susceptible to phishing and social engineering attempts. In addition, technological resources may become strained due to the number of remote users.

The Company also faces potential cybersecurity risks from the use of artificial intelligence and machine learning (AI) tools. The Company, or its customers' sensitive, proprietary, or confidential information could be leaked, disclosed, or revealed as a result of or in connection with employees' or vendors' use of generative AI technologies. In addition, the Company may use AI outputs to inform certain decisions, and AI models may create incomplete, inaccurate, or otherwise flawed outputs, some of which may appear correct. Due to the potential flaws in the use of AI, the Company could make incorrect decisions, including decisions that could bias certain individuals or classes of individuals and adversely impact their rights. As a result, the Company could face adverse consequences, including exposure to reputational and competitive harm, customer loss, and legal liabilities. The AI tools may also be subject to additional, and as yet unidentified, security threats.

The Company depends on third parties to provide services critical to the Company's business, and depends on them to comply with applicable laws and regulations. Additionally, any cybersecurity incidents affecting the information technology systems of third parties could have a material adverse effect on the Company's operations.

The Company depends on third parties to provide services critical to the Company's business, including supplies, ground and air transport of clinical and diagnostic testing supplies and specimens, research products, and people, among other services. Third parties that provide services to the Company are subject to similar risks related to security of customer-related information and compliance with U.S., state, local, or international environmental, health and safety, and privacy and security laws and regulations as the Company. Any failure by third parties to comply with applicable laws, or any failure of third parties to provide services more generally, could have a material impact on the Company, whether because of the loss of the ability to

Index

receive services from the third parties, legal liability of the Company for the actions or inactions of third parties, or otherwise.

In addition, third parties to whom the Company outsources certain services or functions may process personal data, or other confidential information of the Company. A cybersecurity incident affecting these third parties, like the AMCA Incident, could also harm the Company's business, results of operations and reputation.

Risks Related to Regulatory and Compliance Matters

Changes in payer regulations or policies, insurance regulations or approvals, or changes in laws, regulations, or policies in the U.S. or globally, including changes in their interpretation, may adversely affect the Company.

U.S. and state government payers, such as Medicare and Medicaid, as well as insurers, including MCOs, have increased their efforts to control the cost, utilization and delivery of healthcare services. From time to time, Congress has considered and implemented changes in Medicare fee schedules in conjunction with budgetary legislation. The first phase of reductions pursuant to PAMA came into effect on January 1, 2018, and will continue subject to certain delays in implementation and phase-in limits through 2027, and without limitations for subsequent periods. Further reductions due to changes in policy regarding coverage of tests or other requirements for payment, such as prior authorization, diagnosis code and other claims edits, may be implemented from time to time. Medicare reimbursement for pathology services performed by Dx, which are paid for under the PFS, is also subject to statutory and regulatory reduction. Reductions in the reimbursement rates and changes in payment policies of other third-party payers may occur as well. Such changes in the past have resulted in reduced payments as well as added costs and have decreased test utilization for the commercial laboratory industry by adding more complex new regulatory and administrative requirements. Further changes in third-party payer regulations, policies, or laboratory benefit or utilization management programs may have a material adverse effect on Dx's business. Actions by federal and state agencies regulating insurance, including healthcare exchanges, or changes in other laws, regulations, or policies may also have a material adverse effect upon Dx's business.

The Company could face significant monetary damages and penalties and/or exclusion from government programs if it violates anti-fraud and abuse laws.

The Company is subject to extensive government regulation at the federal, state, and local levels in the U.S. and other countries where it operates. The Company’s failure to meet governmental requirements under these regulations, including those relating to billing practices and financial relationships with physicians, hospitals, and health systems, and others could lead to civil and criminal penalties, exclusion from participation in Medicare and Medicaid and possible prohibitions or restrictions on the use of its laboratories. While the Company believes that it is in material compliance with all statutory and regulatory requirements, there is a risk that government authorities might take a contrary position. This risk includes, but is not limited to, the potential that government enforcement authorities may take a contrary position with respect to the Eliminating Kickbacks in Recovery Act, given the lack of associated regulations to clarify or add exceptions. Such occurrences, regardless of their outcome, could damage the Company’s reputation and adversely affect important business relationships.

The Company’s business could be harmed from the loss or suspension of a license or imposition of a fine or penalties under, or future changes in, or interpretations of, the law or regulations of CLIA, Medicare, Medicaid or other national, state, or local agencies in the U.S. and other countries where the Company operates laboratories.

The commercial laboratory testing industry is subject to extensive U.S. regulation, and many of these statutes and regulations have not been interpreted by the courts. CLIA extends federal oversight to virtually all clinical laboratories operating in the U.S. by requiring that they be certified by the federal government or by a federally approved accreditation agency. The sanction for failure to comply with CLIA requirements may be suspension, revocation, or limitation of a laboratory’s CLIA certificate, which is necessary to conduct business, as well as significant fines and/or criminal penalties. In addition, the Company is subject to regulation under state law. State laws may require that laboratories and/or laboratory personnel meet certain qualifications, specify certain quality controls or require maintenance of certain records. The Company also operates laboratories outside of the U.S. and is subject to laws governing its laboratory operations in the other countries where it operates.

Applicable statutes and regulations could be interpreted or applied by a prosecutorial, regulatory or judicial authority in a manner that would adversely affect the Company's business. Potential sanctions for violation of these statutes and regulations include significant fines and the suspension or loss of various licenses, certificates, and authorizations, which could have a material adverse effect on the Company’s business. In addition, compliance with future legislation could impose additional requirements on the Company, which may be costly.

Failure of the Company or its third-party service providers to comply with privacy and data security laws and regulations could result in fines, penalties and damage to the Company’s reputation with customers and have a material adverse effect upon the Company’s business.

Index

If the Company and its third-party service providers do not comply with existing or new laws and regulations related to protecting the privacy and security of personal or health information, it could be subject to monetary fines, civil penalties, litigation, or criminal sanctions.

In the U.S., the Health Insurance Portability and Accountability Act of 1996, the U.S. Health Information Technology for Economic and Clinical Health (HITECH) Act, and their implementing privacy and security regulations (collectively, HIPAA) establish comprehensive standards with respect to the use and disclosure of protected health information (PHI), by covered entities as well as their "business associates" as defined in HIPAA, in addition to setting standards to protect the confidentiality, integrity and security of PHI.

HIPAA restricts the Company’s ability to use or disclose PHI, without patient authorization, for purposes other than payment, treatment or healthcare operations (as defined by HIPAA), except for disclosures for various public policy purposes and other permitted purposes outlined in the privacy regulations. HIPAA provides for significant fines and other penalties for wrongful use or disclosure of PHI in violation of the privacy and security regulations, including potential civil and criminal fines and penalties. The regulations establish a complex framework on a variety of subjects, including:

•the circumstances under which the use and disclosure of PHI are permitted or required without a specific authorization by the patient, including, but not limited to, treatment purposes, activities to obtain payments for the Company’s services, and its healthcare operations activities;

•a patient’s rights to access, amend and receive an accounting of certain disclosures of PHI;

•the content of notices of privacy practices for PHI;

•administrative, technical and physical safeguards required of entities that use or receive PHI; and

•the protection of computing systems maintaining electronic PHI.

The Company has implemented policies and procedures designed to comply with the HIPAA privacy and security requirements as applicable. The privacy and security regulations establish a “floor” and do not supersede state laws that are more stringent. Therefore, the Company is required to comply with both additional federal privacy and security regulations and varying state privacy and security laws. To the extent applicable, newer laws like the California Consumer Privacy Act (“CCPA”) as amended by the California Privacy Rights Act (“CPRA”), the Washington My Health My Data Act, and similar consumer privacy laws in other states, may impose additional obligations on the Company. Federal and state laws that protect the privacy and security of patient information may be subject to enforcement and interpretations by various governmental authorities and courts, resulting in complex compliance issues. In addition, laws regulating artificial intelligence and machine learning, including the use of algorithms and automated processing, may impact the Company and lead to increases in the cost of compliance. Noncompliance with these laws could result in the imposition of fines, penalties, or orders to stop certain activities, and potentially expose the Company to actions for the wrongful use or disclosure of health information or other personal information.

The Company may also be required to comply with the data privacy and security laws of other countries in which it operates or with which it transfers and receives data. For example, the EU's General Data Protection Regulation (GDPR), which took effect May 25, 2018, created a range of compliance obligations for subject companies and imposes penalties for noncompliance of up to the greater of €20 million or 4% of worldwide revenue for the most serious breaches of data protection obligations. The Company has established processes and frameworks to manage compliance with the GDPR. Potential fines and penalties in the event of a violation of the GDPR could have a material adverse effect on the Company’s business and operations. In addition, similar data protection regulations addressing access, use, disclosure and transfer of personal data have been enacted or updated in regions where the Company does business, including in Asia, Latin America, and Europe. The Company expects to make changes to its business practices and to incur additional costs associated with compliance with these evolving and complex regulations.

The Company's international operations could subject it to additional risks and expenses that could adversely impact the business or results of operations.

The Company's international operations expose it to risks from potential failure to comply with foreign laws and regulations that differ from those under which the Company operates in the U.S. In addition, the Company may be adversely affected by other risks of operations in foreign countries, including, but not limited to: changes in reimbursement by foreign governments for services provided by the Company; compliance with export controls and trade regulations; changes in tax policies or other foreign laws; compliance with foreign labor and employee relations laws and regulations; restrictions on currency repatriation; judicial systems that less strictly enforce contractual rights; countries that do not have clear or well-established laws and regulations concerning issues relating to commercial laboratory testing or drug development services; countries that provide less protection for intellectual property rights; and procedures and actions affecting approval, production, pricing, reimbursement and marketing of products and services. Further, international operations could subject the Company to additional expenses that the Company may not fully anticipate, including those related to enhanced time and resources

Index

necessary to comply with foreign laws and regulations, difficulty in collecting accounts receivable and longer collection periods, and difficulties and costs of staffing and managing foreign operations. In some countries, the Company's success will depend in part on its ability to form relationships with local partners. The Company's inability to identify appropriate partners or reach mutually satisfactory arrangements could adversely affect the business and operations.

International operations may increase the Company’s exposure to liabilities under applicable anti-corruption laws.

Anti-corruption laws in the countries where the Company conducts business, including the FCPA, U.K. Bribery Act, and similar laws in other jurisdictions, prohibit companies and their intermediaries from engaging in bribery including improperly offering, promising, paying or authorizing the giving of anything of value to individuals or entities for the purpose of corruptly obtaining or retaining business. The Company operates in parts of the world where corruption may be common and where anti-corruption laws may conflict to some degree with local customs and practices. The Company maintains an anti-corruption program including policies, procedures, training and safeguards in the engagement and management of third parties acting on the Company’s behalf. Despite these safeguards, the Company cannot guarantee protection from corrupt acts committed by employees or third parties associated with the Company. Violations or allegations of violations of anti-corruption laws could have a significant adverse effect on the business or results of operations.

Failure to comply with the regulations of pharmaceutical and medical device regulatory agencies, such as the FDA, the Medicines and Healthcare Products Regulatory Agency in the United Kingdom, the European Medicines Agency, the National Medical Products Administration in China (NMPA), and the Pharmaceuticals and Medical Devices Agency in Japan, could result in fines, penalties, and sanctions against BLS and have a material adverse effect upon the Company.

The operation of BLS's preclinical laboratory facilities and central laboratory operations must conform to good laboratory practice (GLP) and good clinical practice (GCP), as applicable, as well as all other applicable standards and regulations, as further described in Item 1 of Part I of this Annual Report. The business operations of BLS’s clinical and preclinical laboratories also require the import, export and use of medical devices, in vitro diagnostic devices, reagents, and human and animal biological products. Such activities are subject to numerous applicable local and international regulations with which BLS must comply. If BLS does not comply, BLS could potentially be subject to civil, criminal or administrative sanctions and/or remedies, including suspension of its ability to conduct preclinical and clinical studies, and to import or export to or from certain countries, which could have a material adverse effect upon the Company.

Additionally, certain BLS services and activities must conform to current good manufacturing practice (cGMP), as further described in Item 1 of Part I of this Annual Report. Failure to maintain compliance with GLP, GCP, or cGMP regulations and other applicable requirements of various regulatory agencies could result in warning or untitled letters, fines, unanticipated compliance expenditures, suspension of manufacturing, and civil, criminal or administrative sanctions and/or remedies against BLS, including suspension of its laboratory operations, which could have a material adverse effect upon the Company.

Increased regulations and restrictions on the import of research animals, limitations of supply of research animals, and actions of animal rights activists may have an adverse effect on the Company.

BLS's preclinical services utilize animals in preclinical testing of the safety and efficacy of drugs and devices. Such activities are required for the development of new medicines and medical devices under regulatory regimes in the U.S., Europe, Japan, and other countries. Increased regulations and restrictions on the import of research animals into various countries, as well as limitations of supply could impact BLS’s ability to conduct preclinical research and could have an adverse effect on BLS’s financial condition, results of operations, and cash flows. In addition, acts of vandalism and other acts by animal rights activists who object to the use of animals in drug development could have an adverse effect on the Company.

Animal populations may suffer diseases that can damage BLS's inventory, harm its reputation, or result in other liability.

It is important that research products be free of diseases, including infectious diseases. The presence of diseases can distort or compromise the quality of research results, cause loss of animals in BLS’s inventory, result in harm to humans or outside animal populations if the disease is not contained to animals in inventory, or result in other losses. Such results could harm BLS’s reputation or have an adverse effect on BLS's financial condition, results of operations, and cash flows.

Failure to conduct animal research in compliance with animal welfare laws and regulations could result in sanctions and/or remedies against BLS and have a material adverse effect upon the Company.

The conduct of animal research at BLS’s facilities must be in compliance with applicable laws and regulations in the jurisdictions in which those activities are conducted. These laws and regulations include the U.S. Animal Welfare Act (AWA), which governs the care and use of warm-blooded animals for research in the U.S. other than laboratory rats, mice and chickens, and is enforced through periodic inspections by the U.S. Department of Agriculture (USDA). The AWA establishes facility standards regarding several aspects of animal welfare, including housing, ventilation, lighting, feeding and watering, handling,

Index

veterinary care, and recordkeeping. Similar laws and regulations apply in other jurisdictions in which BLS conducts animal research, including the UK, EU, and China. BLS complies with licensing and registration requirement standards set by these laws and regulations in the jurisdictions in which it conducts animal research. If an enforcement agency determines that BLS’s equipment, facilities, laboratories or processes do not comply with applicable standards, it may issue an inspection report documenting the deficiencies and setting deadlines for any required corrective actions. For noncompliance, the agency may take action against BLS that may include fines, suspension and/or revocation of animal research licenses, or confiscation of research animals.

U.S. Food and Drug Administration (FDA) regulation of diagnostic products, increased FDA regulation of laboratory-developed tests (LDTs), and regulation by other countries of diagnostic products could result in increased costs and the imposition of fines or penalties, and could have a material adverse effect upon the Company’s business.

The FDA has regulatory responsibility for instruments, test kits, reagents and other devices used by clinical laboratories. The FDA enforces laws and regulations that govern the development, testing, manufacturing, performance, labeling, advertising, marketing, distribution, and surveillance of diagnostic products, and it regularly inspects and reviews the manufacturing processes and product performance of diagnostic products. Dx’s point-of-care testing devices are subject to regulation by the FDA.

LDTs developed by high complexity clinical laboratories are currently generally offered as services to health care providers under the CLIA regulatory framework administered by CMS, without the requirement for FDA clearance or approval. However, since the 1990s, the FDA has asserted that it has authority to regulate LDTs as medical devices but has exercised enforcement discretion to refrain from systematic regulation of LDTs. In 2014, the FDA issued draft guidance describing how it intended to discontinue its enforcement discretion policy and begin regulating LDTs as medical devices; however, that draft guidance has not been finalized, and the FDA has instead continued its enforcement discretion policy and has indicated that it intends to work with Congress to enact comprehensive legislative reform of diagnostics oversight. In February 2020, the FDA issued a statement with a table of pharmacogenetic associations setting forth certain gene-drug interactions that the agency determined are supported by the scientific literature to help ensure that claims being made for pharmacogenetic tests are grounded in sound science, thereby reducing the risk of enforcement actions with respect to LDTs offering claims consistent with the table. The FDA noted that it could take enforcement actions under the current medical device framework regarding diagnostic claims the agency determines not to be sufficiently supported. In addition, in 2021, the Verifying Accurate, Leading-edge, IVCT Development (VALID) Act was introduced to Congress and provided a framework to change in vitro diagnostics and LDTs to in vitro clinical tests. In 2022, the VALID Act was incorporated into the Senate user fee bill but was not included in the year-end Consolidated Appropriations Act of 2022. Following challenges with passing diagnostics reform legislation, the FDA released a proposed rule to clarify its authority to regulate LDTs as medical devices under the federal Food, Drug, and Cosmetic Act in October 2023. If finalized, FDA would phase out its general enforcement discretion approach for LDTs. Even without issuance of a finalized LDT oversight framework, in light of the April 4, 2019, FDA warning letter issued to Inova Genomics Laboratory related to certain LDTs that Inova offered, the February 2020 pharmacogenetics statement, and the 2023 proposed rule, there may be an increased risk of FDA enforcement actions for laboratory tests offered by companies without FDA clearance or approval. However, the outcome and its ultimate impact on the Company’s business is difficult to predict at this time.

Current FDA regulation of the Company’s diagnostic products and the potential for future increased regulation of the Company’s LDTs in the future could result in increased costs and administrative and legal actions for noncompliance, including warning letters, fines, penalties, product suspensions, product recalls, injunctions, and other civil and criminal sanctions, and could impair the development and commercialization of new tests, which could have a material adverse effect upon the Company.

Regulation of diagnostics products in jurisdictions outside the U.S. in which the Company operates may impact laboratory testing offered by the Company in both Dx and BLS. For example, the European Union In Vitro Diagnostics Regulation (Regulation (EU) 2017/746 (EU IVDR)) established a new legislative framework for in vitro diagnostic devices that are used in certain circumstances, and includes a rule-based classification and quality and safety standards. The EU IVDR, where applicable to BLS's services, could impact BLS's ability to support trials, result in increased costs and administrative and legal actions, and have an adverse effect.

Failure to comply with U.S., state, local, or international environmental, health and safety laws and regulations, including the U.S. Occupational Safety and Health Administration Act and the U.S. Needlestick Safety and Prevention Act, could result in fines, penalties and loss of licensure, and have a material adverse effect upon the Company.

As previously discussed in Item 1 of Part I of this Annual Report, the Company is subject to licensing and regulation under laws and regulations relating to the protection of the environment and human health and safety, including laws and regulations relating to the handling, transportation and disposal of medical specimens, infectious and hazardous waste and radioactive

Index

materials, as well as regulations relating to the safety and health of laboratory employees. Failure to comply with these laws and regulations could subject the Company to denial of the right to conduct business, fines, criminal penalties and/or other enforcement actions that would have a material adverse effect on its business. In addition, compliance with future legislation could impose additional requirements on the Company that may be costly.

Environmental, social and governance (ESG) matters and the perception of the Company’s activities in these areas by stakeholders may impact the Company’s business and reputation.

Governmental authorities, non-governmental organizations, customers, investors, external stakeholders, and employees are increasingly sensitive to ESG concerns, such as diversity and inclusion, climate change, water use, recyclability or recoverability of packaging, and plastic waste. This focus on ESG concerns may lead to new requirements that could result in increased costs associated with developing, manufacturing, and distributing the Company’s services and products. The Company’s ability to compete could also be affected by changing customer preferences and requirements and the failure to meet such customer expectations or demand, whether related to environmental concerns or other ESG matters. While the Company strives to improve its ESG performance, has established certain ESG goals and initiatives, and participates in various third-party assessments and reporting regimens, the Company risks negative stockholder reaction and activism, including from proxy advisory services, as well as damage to its brand and reputation, if the Company fails to meet its goals and initiatives or if the Company is perceived to not be acting responsibly in key ESG areas, including product quality and safety, diversity and inclusion, environmental stewardship, support for local communities, corporate governance and transparency, and addressing human capital factors in the Company’s operations. Responding to these ESG considerations and implementation of the Company’s ESG goals and initiatives involves risks and uncertainties, requires investments, and depends in part on third-party performance or data that is beyond the Company’s control. In addition, some stakeholders may disagree with the Company’s ESG goals and initiatives. If the Company does not meet the evolving and varied ESG expectations of its investors, customers and other stakeholders, the Company could experience reduced demand for its products, loss of customers, and other negative impacts on the Company’s business and results of operations.

Risks Related to Legal Matters

Adverse results in material litigation matters could have a material adverse effect upon the Company’s business.

The Company is currently and may continue to be subject in the ordinary course of business to legal actions related to, among other things, intellectual property disputes, contract disputes, data and privacy issues, professional liability and employee-related matters, which may be or may become material. The Company also has received and may in the future receive inquiries and requests for information from governmental agencies and bodies, including Medicare or Medicaid payers, requesting comment and/or information on various matters, including allegations of billing irregularities, billing and pricing arrangements, or privacy practices that are brought to its attention through audits or third parties. Legal actions can result in substantial monetary damages as well as damage to the Company’s reputation with customers, which could have a material adverse effect upon its business.

The failure to successfully obtain, maintain, and enforce intellectual property rights and defend against challenges to the Company’s intellectual property rights could adversely affect the Company.

Many of the Company’s services, products and processes rely on intellectual property, including patents, copyrights, trademarks, and trade secrets. In some cases, that intellectual property is owned by another party and licensed to the Company, sometimes exclusively. The value of the Company’s intellectual property relies in part on the Company’s ability to maintain its proprietary rights to such intellectual property. The Company has been in the past and may be unable in the future to obtain or maintain the proprietary rights to its intellectual property, to prevent attempted infringement against its intellectual property, or to defend against claims that it is infringing on another party’s intellectual property, and the Company could be adversely affected.

For example, in October 2020, Ravgen Inc. filed a patent infringement lawsuit against the Company alleging infringement of two Ravgen-owned U.S. patents. In September 2022, a jury rendered a verdict in favor of Ravgen on the remaining patent at issue and awarded damages of $272 million. In May 2023, a judge awarded Ravgen additional enhanced damages in the amount of $100 million. The Company strongly disagrees with the verdict, based on a number of legal factors, and will vigorously defend the lawsuit through the appeal process. On June 4, 2021, the Company also instituted proceedings before the Patent Trial and Appeal Board of the U.S. Patent and Trademark Office challenging the validity of the Ravgen patent at issue in the trial. In November 2022, the Patent Trial and Appeal Board issued a decision upholding the validity of the Ravgen patent, and the Company has filed an appeal of this decision.

Adverse effects resulting from the failure to successfully obtain, maintain, and enforce intellectual property rights and defend against challenges to the Company's intellectual property rights could include the Company having to abandon, alter and/or delay the deployment of products, services or processes that rely on such intellectual property; having to procure and pay

Index

for licenses from the holders of intellectual property rights that the Company seeks to use, having to pay damages, fines, court costs and attorney's fees in connection with intellectual property litigation, and reputational damage.

Changes in tax laws and regulations or the interpretation of such may have a significant impact on the financial position, results of operations, and cash flows of the Company.

U.S. and foreign governments continue to review, reform and modify tax laws, including with respect to the Organisation for Economic Co-operation and Development’s base erosion and profit shifting initiative. Changes in tax laws and regulations could result in material changes to the domestic and foreign taxes that the Company is required to provide for and pay.

In addition, the Company is subject to regular audits with respect to its various tax returns and processes in the jurisdictions in which it operates. Errors or omissions in tax returns, process failures or differences in interpretation of tax laws by tax authorities and the Company may lead to litigation, payments of additional taxes, penalties and interest.

Contract services in the drug development industry create liability risks.

In contracting to work on drug development trials and studies, BLS faces potential risks inherent to the provision of diagnostic information services for clinical trial participants. Users of BLS for clinical trials may have a greater sensitivity to errors than the users of services or products that are intended for other purposes, such as research only. Other potential liabilities may include:

•Errors or omissions that create harm to clinical trial subjects during a trial or to consumers of a drug after the trial is completed and regulatory approval of the drug has been granted;

•Risks that animals in BLS’s facilities may be infected with diseases that may be harmful and even lethal to themselves and humans despite preventive measures contained in BLS's business policies, including those for the quarantine and handling of imported animals; and

While BLS endeavors to include in its contracts provisions entitling it to be indemnified and entitling it to a limitation of liability, these provisions are not always successfully obtained and, even if obtained, do not uniformly protect BLS against liability arising from certain of its own actions. BLS could be materially and adversely affected if it were required to pay damages or bear the costs of defending any claim that is not covered by a contractual indemnification provision, or in the event that a party which must indemnify it does not fulfill its indemnification obligations, or in the event that BLS is not successful in limiting its liability or in the event that the damages and costs exceed BLS's insurance coverage. BLS may also be required to agree to contract provisions with clinical site selection or its customers related to the conduct of clinical trials, and BLS could be materially and adversely affected if it were required to indemnify a site or customer against claims pursuant to such contract terms. There can be no assurance that BLS will be able to maintain sufficient insurance coverage on acceptable terms.

Item 1C. CYBERSECURITY

Risk Management and Strategy

Protecting the information maintained by the Company about its patients, customers, colleagues, and partners against external and internal threats is a priority for the Company. Accordingly, the Company invests in the development and implementation of cybersecurity policies, control standards, and control procedures, including a risk management and assessment program, security and event monitoring capabilities, an incident response plan, and other detection, prevention, and protection capabilities, including practices and tools to monitor and mitigate external and insider threats. The Company engages in a risk monitoring process through its Office of Information Security (OIS) within the Information Technology organization that seeks to identify the likelihood and impact of threats to its systems and data, and assesses the effectiveness of the controls in place.

Consistent with business requirements, components of the Company’s information technology and controls are assessed by independent third parties against various frameworks and standards. With the assistance of these frameworks and standards, the Company assesses risks from cybersecurity threats, monitors its information systems for potential vulnerabilities, and assesses those systems pursuant to the Company’s cybersecurity policies, control standards, and control procedures. Mitigation of identified threats and vulnerabilities may be delayed.

The Company has implemented an Incident Response Plan (IR Plan), which is aligned to its overall crisis management program. The IR Plan provides a framework for responding to and managing cybersecurity incidents. The IR Plan identifies applicable requirements for incident response, outlines processes for any applicable reporting, as well as provides protocols for incident evaluation, processes for notification and internal escalation of information to the Company’s senior management, and the Board and/or appropriate Board committees, as applicable. The IR Plan is reviewed, tested, and updated under the leadership of the Company’s Chief Information and Technology Officer (CITO) and Chief Information Risk Officer (CIRO).

The Company’s cybersecurity team also provides enterprise-wide cybersecurity training for employees to maintain and continuously improve the Company’s mitigation against human-driven risk.

Engagement with External Cybersecurity Professionals

The Company engages with third parties to assess the effectiveness of, and assist with, its cybersecurity risk and response systems and processes. These third parties include cybersecurity assessors, consultants, and other cybersecurity professionals who assist in the identification, verification, and validation of cybersecurity risks, as well as support associated mitigation or incident response plans when necessary.

Oversight of Third-Party Service Providers

The Company’s processes also are designed to evaluate the cybersecurity threat risks associated with its use of third-party service providers that have applicable levels of access to the Company’s data or information technology systems. The Company performs due diligence on third parties that have access to its systems, data, or facilities that house such systems or data, and it monitors cybersecurity threat risks identified through such due diligence.

Cybersecurity Incident Impact

The Company describes whether and how risks from identified cybersecurity threats, including as a result of any previous cybersecurity incidents, have materially affected or are reasonably likely to materially affect it, including its business and operating results, financial condition, and impact on the Company’s reputation and customer relationships, under the Summary of Material Risks section of this Annual Report, and under the “Risks Related to Technology and Cybersecurity” heading and subheadings thereunder in Part I, Item 1A. “Risk Factors” of this Annual Report, which disclosures are incorporated by reference herein.

In July 2018, the Company experienced a ransomware incident which affected certain Dx information technology systems. The incident also temporarily affected certain other information technology systems involved in conducting Company-wide operations. An investigation determined that the ransomware did not and could not transfer patient or client data outside of Company systems and that there was no theft or misuse of patient or client data. This incident did not have a material effect on the Company.

On May 14, 2019, Retrieval-Masters Credit Bureau, Inc. d/b/a/ American Medical Collections Agency (AMCA), an external collection agency, notified the Company about a security incident AMCA experienced that may have involved certain personal information about some of the Company's patients (the AMCA Incident). The Company is involved in pending and threatened litigation related to the AMCA Incident, as well as various government and regulatory inquiries and processes. For additional information about the AMCA Incident, see Note 15 Commitments and Contingencies to the Consolidated Financial Statements “Cybersecurity" and “Risk Factors - Risks Related to Technology and Cybersecurity”.

Governance

The Company’s board of directors has oversight responsibility for the Company’s enterprise risk management process and it delegates oversight responsibility for certain significant functional areas of risk management to the board’s committees. The Audit Committee of the board of directors is responsible for oversight and review of the Company’s cybersecurity and other information technology risks, controls, and procedures, including the potential impact of such risks on the Company’s business, financial results, operations, and reputation, as well as the Company’s plans to mitigate cybersecurity risks and to respond to cybersecurity incidents.

The CIRO and CITO routinely present cybersecurity reports to the Audit Committee at its regularly scheduled meetings. These reports may address cyber risks and threats, the status of projects to strengthen the Company’s information security systems, assessments of the Company’s security program, prior incidents, and the emerging cyber threat landscape. In addition, the full Board receives briefings from the CIRO and CITO on at least an annual basis.

Management is responsible for day-to-day assessment and oversight of cybersecurity risks. At the senior management level, the CITO is responsible for overseeing the Company’s information technology systems, technology capabilities, and cybersecurity practices. The CITO has more than 30 years of experience working in information technology-related roles and is a member of the Company’s executive leadership team and reports to the Chief Executive Officer. Prior to joining the Company, the CITO held various chief information officer roles with global companies.

The CIRO, under the direction of the CITO, is responsible for overseeing the OIS. In this role, the CIRO oversees the cyber risk management function, which identifies cybersecurity threats, assesses cybersecurity risks, and supports the CITO and the Company in managing such risks. The CIRO has over 30 years of experience in information security, and prior to joining the Company held various chief information security officer roles, including seven years at a global healthcare company. The CIRO has also served on the board of directors of Health-ISAC, an organization of critical infrastructure owners and operators within the health and public health sectors.

The CITO and CIRO together lead efforts to design, implement and operate controls deemed appropriate for the management of Company information assets and systems. OIS manages the policies, control procedures, and control standards designed to identify, detect, protect against, respond to, and recover from cybersecurity threats and cybersecurity incidents. This group includes a cybersecurity operations team that is responsible for the information technology security monitoring and incident response activities, the latter covering the response coordination to cybersecurity incidents under the leadership and pursuant to the direction of the CIRO. OIS also oversees the Company’s cybersecurity training program for employees.

Item 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (all amounts in millions, except per share amounts or as otherwise noted)

General

During the year ended December 31, 2023, the Company's revenues from continuing operations were $12.2 billion, an increase of 2.5% from $11.9 billion in 2022. The 2.5% increase in revenues for the year ended December 31, 2023, as compared to the corresponding period in 2022 was due to acquisitions, net of divestitures of 1.7%, organic revenue of 0.6%, and favorable foreign currency translation of 0.2%. The 0.6% increase in organic revenue was due to an 8.7% increase in the

Company's organic Base Business (Base Business includes the Company's business operations except for COVID-19 PCR and antibody testing (COVID-19 Testing)), partially offset by an 8.1% decrease in COVID-19 Testing.

The Company defines organic growth as the increase in revenue excluding the year over year impact of acquisitions, divestitures, and currency. Acquisition and divestiture impact is considered for a twelve-month period following the close of each transaction.

On June 30, 2023, the Company completed the previously announced spin-off of Fortrea from the Company.

In June 2023, Fortrea, prior to the spin-off and while a subsidiary of the Company, issued $570.0 of 7.500% senior secured notes due 2030 (the Fortrea Notes). The proceeds from the Fortrea Notes were used to fund cash payments of approximately $1,600.0 to the Company in connection with the spin-off. The Company does not guarantee the Fortrea Notes following the spin-off. Also in June 2023, Fortrea Holdings Inc. entered into three floating secured overnight financing rate (SOFR) credit facilities totaling $1,520.0. These are comprised of $450.0 Revolver maturing June 30, 2028; $500.0 Term Loan A maturing June 30, 2028; and $570.0 Term Loan B maturing June 30, 2030.

Upon closing of the spin-off transaction, Fortrea made a cash distribution to the Company of approximately $1,600.0 as partial consideration for the assets that the Company contributed to Fortrea in connection with the spin-off. The Company used these proceeds toward a 1000.0 accelerated share repurchase program and paying down $300.0 of debt that matured in 2023, with the remaining funds to be returned to shareholders through additional future share repurchases and/or cash dividends.

All current and historical operating results of Fortrea are presented as Discontinued Operations, net of tax, in the consolidated statement of operations. The spin-off is expected to be treated as tax-free for the Company and its shareholders for U.S. federal income tax purposes.

As a result of the spin-off of Fortrea, the Company recast segment results to exclude the historical results of the CDCS business for all periods presented. The remaining operations of the previously reported Drug Development segment has been renamed the Biopharma Laboratory Services segment.

Following the spin-off, the Company believes that it is positioned to:

•launch innovative tests globally, providing patients, physicians, health systems and pharmaceutical companies with access to its advanced science, technology and diagnostic capabilities.

The change in Other, net for the year ended December 31, 2023, as compared to the year ended December 31, 2022, was primarily due to $46.1 of transition services fees charged to Fortrea related to administrative and information technology systems support.

The change in Other, net for the year ended December 31, 2022, as compared to the year ended December 31, 2021, was primarily due to investment losses of $19.6 compared to $61.8 of investment gains in the corresponding period of 2021.

Income Tax Expense


	Years Ended December 31,
	2023			2022			2021
Income tax expense	$	188.5		$	233.9		$	690.0
Income tax expense as a % of income before tax	33.1		%	18.9		%	23.9		%

The increase in effective tax rate as compared with the prior year is primarily attributable to the unfavorable impact of current year goodwill impairment of the early development reporting unit. In contrast, the 2022 goodwill impairment of the early development reporting unit was more than offset by favorable adjustments attributable to research and development tax credits, changes in effective state income tax rates, and deferred tax adjustments.

The 2022 effective tax rate was favorably impacted by the Company's research and development tax credits, changes in effective state income tax rates, and deferred tax adjustments. During the third quarter of 2022, the Company completed a detailed domestic research and development tax credit analysis for the 2019, 2020, and 2021 tax years that resulted in an incremental income tax benefit. The 2021 effective tax rate was favorably impacted by stock-based compensation arrangements that was offset by the deferred revaluation related to the U.K. rate change.

Dx operating income was $1,591.3 for the year ended December 31, 2023, a decrease of 21.4% over operating income of $2,025.5 in the corresponding period of 2022, and Dx operating margin decreased 510 basis points year-over-year. The decrease was primarily due to a reduction in COVID-19 Testing and higher personnel costs, partially offset by a demand in the Base Business.

BLS operating income was $396.3 for the year ended December 31, 2023, an increase of 1.8% from operating income of $389.1 in the corresponding period of 2022, and BLS operating margin decreased 10 basis points year over year. The change was primarily due to demand growth and LaunchPad savings, partially offset by higher personnel expense and non-human primate (NHP) related constraints.

General corporate expenses are comprised primarily of administrative services such as executive management, human resources, legal, finance, corporate affairs, and information technology. Corporate expenses were $644.1 for the year ended December 31, 2023, an increase of 37.4% over corporate expenses of $468.8 in the corresponding period of 2022, primarily due to spin-off transaction costs, personnel costs, bonus allocation, and research and development costs.

Dx operating income was $2,025.5 for the year ended December 31, 2022, a decrease of 36.8% over operating income of $3,205.6 in the corresponding period of 2021, and Dx operating margin decreased 890 basis points year over year. The decrease in operating income and margin were primarily due to a reduction in COVID-19 Testing, higher personnel expense, the mix impact from the integration of Ascension's laboratory business, partially offset by organic Base Business growth.

BLS operating income was $389.1 for the year ended December 31, 2022, a decrease of 22.3% from operating income of $501.0 in the corresponding period of 2021, and BLS operating margin decreased 310 basis points year over year. The decrease was primarily due to a reduction in COVID-19 Testing, a reduction in COVID-19 related work, and other inflationary costs. These impacts were partially offset by Base Business growth and LaunchPad savings.

General corporate expenses are comprised primarily of administrative services such as executive management, human resources, legal, finance, corporate affairs, and information technology. Corporate expenses were $468.8 for the year ended December 31, 2022, an increase of 15.9% over corporate expenses of $404.5 in the corresponding period of 2021, primarily due to higher personnel costs, bonus allocation, research and development costs, and other costs.

Liquidity, Capital Resources and Financial Position

The Company's strong cash-generating capability and financial condition typically have provided ready access to capital markets. The Company's principal source of liquidity is operating cash flow, supplemented by proceeds from debt offerings. The Company's senior unsecured revolving credit facility is further discussed in Note 11 Debt to the Company's Consolidated Financial Statements.

Index

In summary the Company's cash flows were as follows:


	For the Year Ended December 31,
	2023		2022		2021
Net cash provided by continuing operating activities	$	1,202.3	$	1,764.8	$	2,846.3
Net cash used for continuing investing activities	(1,146.8)		(1,599.6)		(845.7)

Net change in cash and cash equivalents	$	106.8	$	(1,042.7)	$	151.9

Cash and Cash Equivalents

Cash and cash equivalents at December 31, 2023 and 2022 totaled $536.8 and $320.6, respectively. Cash and cash equivalents consist of highly liquid instruments, such as time deposits and other money market investments, which have original maturities of three months or less.

Cash Flows from Operating Activities

During the year ended December 31, 2023, the Company's continuing operations provided $1,202.3 of cash as compared to $1,764.8 in 2022 and $2,846.3 in 2021. The $562.5 decrease in cash provided from operations in 2023 as compared with the corresponding 2022 period was primarily due to lower COVID-19 Testing earnings, spin-off related items and higher working capital, partially offset by increased Base Business earnings. The $1,081.5 decrease in cash provided from operations in 2022 as compared with the corresponding 2021 period was primarily due to lower COVID-19 Testing.

Cash Flows from Investing Activities

Net cash used by continuing investing activities for the year ended December 31, 2023 was $1,146.8 as compared to net cash used by continuing investing activities of $1,599.6 for the year ended December 31, 2022 and $845.7 for the year ended December 31, 2021. The $452.8 decrease in net cash used by investing activities for the year ended December 31, 2023 as compared to the year ended December 31, 2022, was primarily due to a year over year decrease of $492.5 in cash paid for acquisitions. The $753.9 increase in net cash used by investing activities for the year ended December 31, 2022 as compared to the year ended December 31, 2021, was primarily due to a year over year increase of $667.1 in cash paid for acquisitions and a year over year decrease in proceeds from sale of $85.9.

Capital expenditures were $453.6, $429.3, and $421.5 for the years ended December 31, 2023, 2022, and 2021, respectively. Capital expenditures in 2023 were 3.7% of revenues, primarily in connection with projects to support growth in the Company's core businesses. The Company intends to continue to pursue acquisitions to drive growth, to make important investments in its business, including in information technology, and to improve efficiency and enable the execution of the Company's mission. Such expenditures are expected to be funded by cash flow from operations or, as needed, through borrowings under debt facilities, including the Company's revolving credit facility or any successor facility. The Company expects capital expenditures in 2024 to be approximately 3.5% of revenues, primarily in connection with projects to support growth in the Company's core businesses, facility updates, projects related to LaunchPad, and further acquisition integration initiatives.

Cash Flows from Financing Activities

Net cash used in continuing financing activities for the year ended December 31, 2023 was $1,559.0 compared to cash used in continuing financing activities of $1,322.2 for the year ended December 31, 2022. This movement in cash within financing activities for 2023, as compared to 2022, was primarily a result of $1,000.0 of share repurchases and $300.0 in senior note repayments in 2023 compared to $1,100.0 of share repurchases in 2022 and the commencement of quarterly dividend payments in the second quarter of 2022.

On May 26, 2021, the Company issued new senior notes representing $1,000.0 in debt securities and consisting of $500.0 aggregate principal amount of 1.55% senior notes due 2026 and $500.0 aggregate principal amount of 2.70% senior notes due 2031. Interest on these notes is payable semi-annually in arrears on June 1 and December 1 of each year, commencing on December 1, 2021. Net proceeds from the offering of these notes were $989.4 after deducting underwriting discounts and other expenses of the offering. The net proceeds were used to redeem, prior to maturity, the Company's outstanding 3.20% senior notes due 2022 and 3.75% senior notes due 2022.

During the second quarter of 2021, the Company entered into fixed-to-variable interest rate swap agreements for its 2.70% senior notes due 2031 with an aggregate notional amount of $500.0 and variable interest rates based on three-month LIBOR (changed to SOFR in 2023) plus 1.0706%. These instruments are designated as hedges against changes in the fair value of a portion of the Company's long-term debt. The aggregate fair value of $69.6 at December 31, 2023, was included as a

Index

component of other long-term liabilities and deducted from the reported value of the senior notes.

On April 30, 2021, the Company amended and restated its revolving credit facility. It consists of a five-year revolving facility in the principal amount of up to $1,000.0, with the option of increasing the facility by up to an additional $500.0, subject to the agreement of one or more new or existing lenders to provide such additional amounts and certain other customary conditions. The Company is required to pay a facility fee on the aggregate commitments under the revolving credit facility, at a per annum rate ranging from 0.100% to 0.225%, depending on the Company’s debt ratings. Borrowings under the revolving credit facility will accrue interest at a per annum rate equal to, at the Company’s election, either (x) a LIBOR (changed to SOFR in 2023) rate plus a margin ranging from 0.775% to 1.275% or (y) a base rate plus a margin ranging from 0% to 0.275%, in each case, depending on the Company’s debt ratings.

The Company continues to evaluate its outstanding debt portfolio to take advantage of market conditions that would allow the Company to reduce its interest rate or financing risk and provide a lower long-term borrowing cost. The Company anticipates that it will refinance the $1,000.0 in debt coming due during 2024.

Under the Company's revolving credit facility, the Company is subject to negative covenants limiting subsidiary indebtedness and certain other covenants typical for investment grade-rated borrowers and the Company is required to maintain certain leverage ratios. The Company was in compliance with all covenants under the revolving credit facility at December 31, 2023, and expects that it will remain in compliance with its existing debt covenants for the next twelve months.

During 2023, the Company repurchased 4.8 shares of its Common Stock at an average price per share of $206.85 for a total cost of $1,000.0. The Company has accrued $9.0 of excise tax related to this accelerated share repurchase which will be paid in April 2024. At the end of 2023, the Company had outstanding authorization from the Board to purchase $530.4 of Company Common Stock. The repurchase authorization has no expiration date.

During the year ended December 31, 2022, the Company purchased 4.7 shares of its Common Stock at an average price per share of $233.48 per share for a total cost of $1,100.0. When the Company repurchases shares, the amount paid to repurchase the shares in excess of the par or stated value is allocated to additional paid-in-capital unless subject to limitation or the balance in additional paid-in-capital is exhausted. Remaining amounts are recognized as a reduction in retained earnings.

For the year ended December 31, 2023, the Company paid $254.0 in Common Stock dividends. On January 12, 2024, the Company announced a cash dividend of $0.72 per share of Common Stock for the first quarter, or approximately $61.5 in the aggregate. The dividend will be payable on March 13, 2024, to stockholders of record of all issued and outstanding shares of Common Stock as of the close of business on February 27, 2024. The declaration and payment of any future dividends will be at the discretion of the Company's board of directors.

Credit Ratings

The Company’s investment grade debt ratings from Moody’s and Standard & Poor's (S&P) contribute to its ability to access capital markets.

Off-Balance Sheet Arrangements

The Company does not have transactions or relationships with “special purpose” entities, and the Company does not have any off-balance sheet financing other than normal operating leases and letters of credit.

Other Commercial Commitments

As of December 31, 2023, the Company provided letters of credit aggregating approximately $91.3, primarily in connection with certain insurance programs which are renewed annually.

The contractual value of the noncontrolling interest put in the Company's Ontario subsidiary totaled $15.5 and $15.0 at December 31, 2023, and 2022, respectively, and has been classified as mezzanine equity in the Company's consolidated balance sheet.

Based on current and projected levels of cash flows from operations, coupled with availability under its revolving credit facility, the Company believes it has sufficient liquidity to meet both its anticipated short-term and long-term cash needs for the next 12 months and the reasonably foreseeable future; however, the Company continually reassesses its liquidity position in light of market conditions and other relevant factors.

Critical Accounting Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reported periods.

Index

While the Company believes these estimates are reasonable and consistent, they are by their very nature estimates of amounts that will depend on future events. Accordingly, actual results could differ from these estimates. The Company’s Audit Committee periodically reviews the Company’s significant accounting policies. The Company’s critical accounting policies arise in conjunction with the following:

•Revenue recognition;

•Business combinations;

•Income taxes;

•Goodwill and indefinite-lived assets; and

•Legal contingencies.

Revenue Recognition

Within the Dx segment, a revenue transaction is initiated when Dx receives a requisition order to perform a diagnostic test. The information provided on the requisition form is used to determine the party that will be billed for the testing performed and the expected reimbursement. Dx recognizes revenue and satisfies its performance obligation for services rendered when the testing process is complete and the associated results are reported. The Dx segment also enters into lab management agreements which have monthly and non-testing based fees which are recognized each month as the services are provided. Revenues are distributed among four payer portfolios - clients, patients, Medicare and Medicaid and third party. Dx considers negotiated discounts and anticipated adjustments, including historical collection experience for the payer portfolio, when revenues are recorded.

The following are descriptions of the Dx payer portfolios:

Clients

Client payers represent the portion of Dx’s revenue related to physicians, hospitals, health systems, accountable care organizations, employers and other entities where payment is received exclusively from the entity ordering the testing service. Generally, client revenues are recorded on a fee-for-service basis at Dx’s client list price, less any negotiated discount. A portion of client billing is for laboratory management services, collection kits and other non-testing services or products. In these cases, revenue is recognized when services are rendered or delivered.

Patients

This portfolio includes revenue from uninsured patients and member cost-share for insured patients (e.g., coinsurance, deductibles and non-covered services). Uninsured patients are billed based upon Dx’s patient fee schedules, net of any discounts negotiated with physicians on behalf of their patients. Dx bills insured patients as directed by their health plan and after consideration of the fees and terms associated with an established health plan contract.

Medicare and Medicaid

This portfolio relates to fee-for-service revenue from traditional Medicare and Medicaid programs. Net revenue from these programs is based on the fee schedule established by the related government authority. In addition to contractual discounts, other adjustments including anticipated payer denials are considered when determining net revenue. Any remaining adjustments to revenue are recorded at the time of final collection and settlement. These adjustments are not material to Dx’s results of operations in any period presented.

Third Party

Third party includes revenue related to MCOs. The majority of Dx's third-party revenue is reimbursed on a fee-for-service basis. These payers are billed at Dx's established list price and revenue is recorded net of contractual discounts. The majority of Dx’s MCO revenues are recorded based upon contractually negotiated fee schedules with revenues for non-contracted MCOs recorded based on historical reimbursement experience.

Third-party reimbursement is also received through capitation agreements with MCOs and independent physician associations (IPAs). Under capitated agreements, revenue is recognized based on a negotiated per-member, per-month payment for an agreed upon menu of tests, or based upon the proportionate share earned by Dx from a capitation pool. When the agreed upon reimbursement is based solely on an established rate per member, revenue is not impacted by the volume of testing performed. Under a capitation pool arrangement, the aggregate value of an established rate per member is distributed based on the volume and complexity of the procedures performed by laboratories participating in the agreement. Dx recognizes revenue monthly, based upon the established capitation rate or anticipated distribution from a capitated pool.

Dx has a formal process to estimate implicit price concessions for uncollectable accounts. The majority of Dx's collection risk is related to accounts receivable from both insured and uninsured patients who are unwilling or unable to pay. Anticipated

Index

write-offs are recorded as adjustments to revenue at an amount considered necessary to record the segment's revenue at its net realizable value. In addition to contractual discounts, other adjustments including anticipated payer denials and other external factors that could affect the collectability of its receivables are considered when determining revenue and the net receivable amount. Any remaining adjustments to revenue are recorded at the time of final collection and settlement. These adjustments are not material to Dx's results of operations in any period presented.

BLS

Fixed-price contracts are typically recognized as revenue over time based on a proportional-performance basis, using either input or output methods that are specific to the service provided. In an output method, revenue is determined by dividing the actual units of output achieved by the total units of output required under the contract and multiplying that percentage by the total contract value. When using an input method, revenue is recognized by dividing the actual costs incurred by the total estimated cost expected to complete the contract, and multiplying that percentage by the total contract value. Contract costs principally include direct labor costs, research model costs and allocated overhead costs. The estimate of total costs expected to complete the contract requires significant judgment and these estimates are reviewed periodically. Any adjustments to these estimates are recognized on a cumulative catch-up basis in the period they become known.

Fee-for-service contracts are typically priced based on transaction volume or time and materials. For volume-based contracts the contract value is entirely variable and revenue is recognized as the specific product or service is completed. For services billed based on time and materials, revenue is recognized using the right to invoice practical expedient.

Contracts are often modified to account for changes in contract specifications and requirements. Generally, when contract modifications create new performance obligations, the modification is considered to be a separate contract and revenue is recognized prospectively. When contract modifications change existing performance obligations, the impact on the existing transaction price and measure of progress for the performance obligation to which it relates is generally recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis.

Most contracts are terminable with or without cause by the customer, either immediately or upon notice. These contracts often require payment to BLS of expenses incurred and fees earned to date and, in some cases, a termination fee or a payment to BLS of some portion of the fees or profits that could have been earned by BLS under the contract if it had not been terminated early. Termination fees are included in revenues when services have been performed and realization is assured.

BLS incurs sales commissions in the process of obtaining contracts with customers, which are recoverable through the service fees in the contract. Sales commissions that are payable upon contract award are recognized as assets and amortized over the expected contract term, along with related payroll tax expense. The amortization of commission expense is based on the weighted average contract duration for all commissionable awards in the respective business in which the commission expense is paid, which approximates the period over which goods and services are transferred to the customer. The amortization period of sales commissions ranges from approximately 1 to 5 years, depending on the business. For businesses that enter primarily short-term contracts, BLS applies the practical expedient which allows costs to obtain a contract to be expensed when incurred if the amortization period of the assets that would otherwise have been recognized is one year or less. Amortization of assets from sales commissions is included in selling, general, and administrative expense.

BLS incurs costs to fulfill contracts with customers, which are recoverable through the service fees in the contract. Contract fulfillment costs include software implementation costs and setup costs for certain services. These costs are recognized as assets and amortized over the expected term of the contract to which the implementation relates, which is the period over which services are expected to be provided to the customer. This period typically ranges from 2 to 5 years. Amortization of deferred contract fulfillment costs is included in cost of goods sold.

Business Combinations

The Company accounts for business combination transactions under the acquisition method of accounting and reported the results of operations of the acquired entities from its respective date of acquisition. Assets acquired were recorded at their

Index

estimated fair values as of the acquisition date. Estimated fair values were based on various valuation methodologies, including an income approach using primarily discounted cash flow techniques for the customer relationships intangible assets. The aforementioned income methods utilize management's estimates of future operating results and cash flows discounted using a weighted-average cost of capital that reflects market participant assumptions. The excess of the fair value of the consideration conveyed over the fair value of the assets acquired was recorded as goodwill. The goodwill reflects management's expectations of the ability to gain access to and penetrate the acquired entities' historical patient base and the benefits of being able to leverage operational efficiencies with favorable growth opportunities based on positive demographic trends in the market.

Income Taxes

The Company accounts for income taxes utilizing the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and for tax loss carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company does not recognize a tax benefit, unless the Company concludes that it is more likely than not that the benefit will be sustained on audit by the taxing authority based solely on the technical merits of the associated tax position. If the recognition threshold is met, the Company recognizes a tax benefit measured at the largest amount of the tax benefit that the Company believes is greater than 50% likely to be realized. The Company records interest and penalties in income tax expense.

Goodwill and Indefinite-Lived Assets

The Company assesses goodwill and indefinite-lived intangibles for impairment at least annually or whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. The annual impairment test for goodwill includes an option to perform a qualitative assessment of whether it is more likely than not that a reporting unit's fair value is less than its carrying value. Reporting units are businesses with discrete financial information that is available and reviewed by management. If the Company determines that it is more likely than not that the fair value of a reporting unit is less than its carrying value, then the Company performs the quantitative goodwill impairment test. The Company may also choose to bypass the qualitative assessment for any reporting unit in its goodwill assessment and proceed directly to performing the quantitative assessment. The Company recognizes an impairment charge for the amount by which the reporting unit's carrying amount exceeds its fair value.

In the qualitative assessment, the Company considers relevant events and circumstances for each reporting unit, including (i) current year results, (ii) financial performance versus management’s annual and five-year strategic plans, (iii) changes in the reporting unit carrying value since prior year, (iv) industry and market conditions in which the reporting unit operates, (v) macroeconomic conditions, including discount rate changes, and (vi) changes in products or services offered by the reporting unit. If applicable, performance in recent years is compared to forecasts included in prior quantitative valuations. Based on the results of the qualitative assessment, if the Company concludes that it is not more likely than not that the fair value of the reporting unit is less than its carrying values of the reporting unit, then no quantitative assessment is performed.

The quantitative assessment includes the estimation of the fair value of each reporting unit as compared to the carrying value of the reporting unit. The Company estimates the fair value of a reporting unit using both income-based and market-based valuation methods. The income-based approach is based on the reporting unit's forecasted future cash flows that are discounted to the present value using the reporting unit's weighted average cost of capital. For the market-based approach, the Company utilizes a number of factors such as publicly available information regarding the market capitalization of the Company as well as operating results, business plans, market multiples, and present value techniques. Based upon the range of estimated values developed from the income and market-based methods, the Company determines the estimated fair value for the reporting unit. If the estimated fair value of the reporting unit exceeds the carrying value, the goodwill is not impaired and no further review is required.

The income-based fair value methodology requires management's assumptions and judgments regarding economic conditions in the markets in which the Company operates and conditions in the capital markets, many of which are outside of management's control. At the reporting unit level, fair value estimation requires management's assumptions and judgments regarding the effects of overall economic conditions on the specific reporting unit, along with assessment of the reporting unit's strategies and forecasts of future cash flows. Forecasts of individual reporting unit cash flows involve management's estimates and assumptions regarding:

•Annual cash flows, on a debt-free basis, arising from future revenues and profitability, changes in working capital, capital spending and income taxes for at least a five-year forecast period.

Index

•A terminal growth rate for years beyond the forecast period. The terminal growth rate is selected based on consideration of growth rates used in the forecast period, historical performance of the reporting unit and economic conditions.

•A discount rate that reflects the risks inherent in realizing the forecasted cash flows. A discount rate considers the risk-free rate of return on long-term treasury securities, the risk premium associated with investing in equity securities of comparable companies, the beta obtained from the comparable companies and the cost of debt for investment grade issuers. In addition, the discount rate may consider any -specific risk in achieving the prospective financial information.

Under the market-based fair value methodology, judgment is required in evaluating market multiples and recent transactions. Management believes that the assumptions used for its impairment tests are representative of those that would be used by market participants performing similar valuations of the reporting units.

Management performed its annual goodwill and intangible asset impairment testing as of the beginning of the fourth quarter of 2023. The Company elected to perform the qualitative assessment for goodwill and intangible assets for the domestic Dx and clinical trials testing solutions (CTTS) BLS reporting units and a quantitative assessment for the early development (ED) BLS reporting unit and the Canadian reporting unit, which includes indefinite-lived assets consisting of acquired Canadian licenses. Based upon the results of the qualitative and quantitative assessments, the Company concluded that the fair values of its domestic Dx, CTTS and Canadian reporting units, as of October 1, 2023, were greater than the carrying values. However, due to lower demand in the ED reporting unit in late 2023 which the Company anticipates will continue into early 2024, there is an expectation of lower near term revenue and profitability. Therefore, the Company concluded that the fair value of the ED reporting unit was less than carrying value and recorded a goodwill impairment of $333.6 in the BLS segment.

Although the Company believes that the current assumptions and estimates used in its goodwill analysis are reasonable, supportable, and appropriate, continued efforts to maintain or improve the performance of these businesses could be impacted by unfavorable or unforeseen changes which could impact the existing assumptions used in the impairment analysis. Various factors could reasonably be expected to unfavorably impact existing assumptions: primarily delays in new customer bookings and the related delay in revenue from new customers, increases in customer termination activity or increases in operating costs. Accordingly, there can be no assurance that the estimates and assumptions made for the purposes of the goodwill impairment analysis will prove to be accurate predictions of future performance. It is possible that the Company's conclusions regarding impairment or recoverability of goodwill or intangible assets in any reporting unit could change in future periods. There can be no assurance that the estimates and assumptions used in the Company's goodwill and intangible asset impairment testing performed as of the beginning of the fourth quarter of 2023 will prove to be accurate predictions of the future, if, for example, (i) the businesses do not perform as projected, (ii) overall economic conditions in 2023 or future years vary from current assumptions (including changes in discount rates), (iii) business conditions or strategies for a specific reporting unit change from current assumptions, including loss of major customers, (iv) investors require higher rates of return on equity investments in the marketplace or (v) enterprise values of comparable publicly traded companies, or actual sales transactions of comparable companies, were to decline, resulting in lower multiples of revenues and EBITDA.

Legal Contingencies

The Company is involved from time to time in various claims and legal actions, including arbitrations, class actions, and other litigation (including those described in more detail below), arising in the ordinary course of business. These matters include, but are not limited to, intellectual property disputes, commercial and contract disputes, professional liability claims, employee-related matters, transaction related disputes, securities and corporate law matters, and inquiries, including subpoenas and other civil investigative demands, from governmental agencies, Medicare or Medicaid payers and MCOs reviewing billing practices or requesting comment on allegations of billing irregularities that are brought to their attention through billing audits or third parties.

The Company also is named from time to time in suits brought under the qui tam provisions of the False Claims Act and comparable state laws. These suits typically allege that the Company has made false statements and/or certifications in connection with claims for payment from U.S. federal or state healthcare programs. The suits may remain under seal (hence, unknown to the Company) for some time while the government decides whether to intervene on behalf of the qui tam plaintiff. Such claims are an inevitable part of doing business in the healthcare field today.

The Company believes that it is in compliance in all material respects with all statutes, regulations, and other requirements applicable to its commercial laboratory operations and drug development support services. The healthcare diagnostics and drug development industries are, however, subject to extensive regulation, and the courts have not interpreted many of the applicable statutes and regulations. Therefore, the applicable statutes and regulations could be interpreted or applied by a prosecutorial, regulatory, or judicial authority in a manner that would adversely affect the Company. Potential sanctions for violation of these

Index

statutes and regulations include significant civil and criminal penalties, fines, the loss of various licenses, certificates and authorizations, additional liabilities from third-party claims, and/or exclusion from participation in government programs.

The Company records an aggregate legal reserve, which is determined using calculations based on historical loss rates and assessment of trends experienced in settlements and defense costs. In accordance with FASB Accounting Standards Codification Topic 450 “Contingencies,” the Company establishes reserves for judicial, regulatory, and arbitration matters outside the aggregate legal reserve if and when those matters present loss contingencies that are both probable and estimable and would exceed the aggregate legal reserve. If the reasonable estimate of a known or probable loss is a range, and no amount within the range is a better estimate than any other, the minimum amount of the range is accrued. If a loss is reasonably possible but not known or probable, and may be reasonably estimated, the estimated loss or range of loss is disclosed. For more information about legal contingencies, see Note 15 Commitments and Contingencies to the Consolidated Financial Statements.

Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK (dollar in millions)

Market risk is the potential loss arising from adverse changes in market rates and prices, such as foreign currency exchange rates, interest rates and other relevant market rate or price changes. In the ordinary course of business, the Company is exposed to various market risks, including changes in foreign currency exchange and interest rates, and the Company regularly evaluates the exposure to such changes. The Company addresses its exposure to market risks, principally the market risks associated with changes in foreign currency exchange rates and interest rates, through a controlled program of risk management that includes, from time to time, the use of derivative financial instruments such as foreign currency forward contracts, cross currency swaps and interest rate swap agreements. The Company does not hold or issue derivative financial instruments for trading purposes.

Foreign Currency Exchange Rates

Approximately 12.9% and 13.8% of the Company's revenues for the year ended December 31, 2023 and 2022, respectively, were denominated in currencies other than the U.S. dollar (USD). The Company's financial statements are reported in USD and, accordingly, fluctuations in exchange rates will affect the translation of revenues and expenses denominated in foreign currencies into USD for purposes of reporting the Company's consolidated financial results. In both 2023 and 2022, the most significant currency exchange rate exposures were to the Canadian dollar, Swiss franc, euro and British pound. Excluding the impacts from any outstanding or future hedging transactions, a hypothetical change of 10% in average exchange rates used to translate all foreign currencies to USD would have impacted income before income taxes for 2023 by approximately $24.1. Gross accumulated currency translation adjustments recorded as a separate component of shareholders’ equity were $183.1 and $(336.4) at December 31, 2023, and 2022, respectively. The Company does not have significant operations in countries in which the economy is considered to be highly inflationary.

The Company earns revenue from service contracts over a period of several months and, in some cases, over a period of several years. Accordingly, exchange rate fluctuations during this period may affect the Company's profitability with respect to such contracts. The Company is also subject to foreign currency transaction risk for fluctuations in exchange rates during the period of time between the consummation and cash settlement of transactions. The Company limits its foreign currency transaction risk through exchange rate fluctuation provisions stated in some of its contracts with customers, or it may hedge transaction risk with foreign currency forward contracts. At December 31, 2023, the Company had 9 open foreign exchange forward contracts with various amounts maturing monthly through January 2024 with a notional value totaling approximately $305.8. At December 31, 2022, the Company had 27 open foreign exchange forward contracts with various amounts maturing monthly through January 2023 with a notional value totaling approximately $629.5.

The Company is party to USD to Swiss Franc cross-currency swap agreements with a notional amount of $600.0, maturing in 2024 and 2025, as a hedge against the impact of foreign exchange movements on its net investment in its Swiss Franc functional currency subsidiary.

Interest Rates

Some of the Company's debt is subject to interest at variable rates. As a result, fluctuations in interest rates affect the Company's financial results. The Company attempts to manage interest rate risk and overall borrowing costs through an appropriate mix of fixed and variable rate debt including the utilization of derivative financial instruments, primarily interest rate swaps.

Borrowings under the Company's term loan credit facilities and revolving credit facility are subject to variable interest rates, unless fixed through interest rate swaps or other agreements.

In May, 2021, to hedge against changes in the fair value portion of the Company's long-term debt, the Company entered into fixed-to-variable interest rate swap agreements for the 2.70% senior notes due 2031 with an aggregate notional value of $500.0 and variable interest rates based on three-month LIBOR (changed to SOFR in 2023) plus 1.0706%.

Item 9A. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

As of the end of the period covered by this Annual Report, the Company carried out under the supervision and with the participation of the Company’s management, including the Company’s principal executive officer and principal financial officer, an evaluation of the effectiveness of the Company's disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended). Based upon this evaluation, the Company’s principal executive officer and principal financial officer concluded that the Company’s disclosure controls and procedures were effective as of the end of the period covered by this Annual Report.

Changes in Internal Control over Financial Reporting

There have been no changes in the Company’s internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) during the quarter ended December 31, 2023, that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Report of Management on Internal Control over Financial Reporting

The Company's management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934).

The internal control over financial reporting at the Company was designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the U.S. Internal control over financial reporting includes those policies and procedures that:

•pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company;

•provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with accounting principles generally accepted in the U.S.;

•provide reasonable assurance that receipts and expenditures of the Company are being made only in accordance with authorization of management and directors of the Company; and

•provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of assets that could have a material effect on the consolidated financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.

The Company's management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2023. Management based this assessment on criteria for effective internal control over financial reporting described in “Internal Control - Integrated Framework 2013” issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this assessment, the Company's management determined that, as of December 31, 2023, the Company maintained effective internal control over financial reporting. Management reviewed the results of its assessment with the Audit Committee of the Company’s Board.

Deloitte and Touche LLP, an independent registered public accounting firm, who audited and reported on the consolidated financial statements of the Company included in this Annual Report, also audited the effectiveness of the Company’s internal control over financial reporting as of December 31, 2023, as stated in its report, which is included herein immediately preceding the Company’s audited financial statements.

We have audited the accompanying consolidated balance sheets of Laboratory Corporation of America Holdings and subsidiaries (the “Company”) as of December 31, 2023, and 2022, the related consolidated statements of operations, comprehensive earnings, changes in shareholders’ equity, and cash flows, for each of the three years in the period ended December 31, 2023, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023, and 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 26, 2024, expressed an unqualified opinion on the Company’s internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current-period audit of the financial statements that were communicated or required to be communicated to the audit committee and that (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Valuation of Labcorp Diagnostics (Dx) Segment Net Accounts Receivable— Refer to Note 3 to the consolidated financial statements

Critical Audit Matter Description

The Company recognizes Dx revenue and accounts receivable net of negotiated discounts and anticipated adjustments, including historical collection experience for each of its four payer portfolios (clients, patients, Medicare & Medicaid, and third party). Management has a formal process to estimate implicit price concessions for uncollectable accounts. Anticipated write-offs are recorded as adjustments to revenue at an amount considered necessary to record revenue at its net realizable value. In addition to negotiated contractual discounts, other adjustments including anticipated payer denials and other external factors that could affect the collectability of its receivables are considered when determining revenue and the net receivable amount.

Given the significant judgment and estimates necessary to determine the net realizable value of accounts receivable related to the Dx segment, auditing such estimates required extensive audit effort and a high degree of auditor judgment when performing audit procedures and evaluating the results of those procedures.

F-2

Index

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to Dx Net Accounts Receivable included the following, among others:

•We tested the effectiveness of controls over the valuation of net accounts receivable.

•We evaluated management’s methodology for recording Dx net accounts receivable by performing a retrospective comparison of actual cash collected to the prior year estimate of net accounts receivable.

•We developed an independent estimate of net accounts receivable by taking into consideration historical collections, write-offs, and other relevant internal and external factors.

•We tested the completeness and accuracy of underlying historical data used as an input to management’s methodology and our independent estimate.

Tax Free Spin-Off – Refer to Note 2 to the consolidated financial statements

Critical Audit Matter Description

On June 30, 2023, the Company completed the spin-off of its Clinical Development and Commercialization Services business comprised of certain clinical research business units within the former Drug Development segment into a standalone, publicly traded company named Fortrea Holdings, Inc. (Fortrea). The transaction was executed by distributing shares of Fortrea to the Company’s shareholders (the “Distribution”). The Company concluded the Distribution to be a tax-free transaction for U.S. Federal income tax purposes. We identified the Company’s conclusion that the Distribution was a tax-free transaction for U.S. federal income tax purposes to be a critical audit matter because of the complexity of the interpretation and application of the U.S. Internal Revenue Code (the “Code”), the materiality of the potential tax consequences, and the need to involve our income tax specialists when performing audit procedures to evaluate the qualification of the Distribution as a tax-free transaction.

How the Critical Audit Matter Was Addressed in the Audit

With the assistance of our income tax specialists, the audit procedures we performed related to the Company’s conclusion that the Distribution was a tax-free transaction for U.S. federal income tax purposes included the following, among others:

• We tested the effectiveness of controls over the Company’s conclusion that the Distribution was a tax-free transaction.

• We inspected the Private Letter Ruling (PLR) received by the Company from the U.S. Internal Revenue Service and the external opinions received by the Company from third-party advisors, which were relied upon in the Company’s evaluation of whether the Distribution qualified as a tax-free transaction.

• We evaluated the key factors addressed in the PLR and external opinions regarding the qualification of the Distribution as a tax-free transaction in comparison to the corresponding criteria prescribed by the Code, including interpretations of the Code and related statutes.

• We evaluated the tax-free transaction materials prepared by the Company and used in its evaluation of whether the Distribution qualified as a tax-free transaction.

• We searched for contradictory evidence regarding the qualification of the Distribution as a tax-free transaction by reading relevant documentation, such as income tax returns and historical financial, tax, and legal information, of the Company and the legal entities included in the Distribution, as applicable.

Goodwill – Reporting Unit within the BioPharma Laboratory Services (BLS) Segment – Refer to Notes 1 and 8 to the consolidated financial statements

Critical Audit Matter Description

The Company assesses goodwill for impairment at least annually or whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. The Company recognizes an impairment charge for the amount by which a reporting unit's carrying amount exceeds its fair value. Fair value of a reporting unit is estimated using both market-based valuation and income-based valuation approaches. Management’s impairment assessments utilize significant judgments and assumptions related to the market multiples selected for the market-based valuation approach and the related estimates of cash flows arising from future revenues and profitability, terminal growth rates, and the discount rate used in the income-based valuation approach.

The Company performed impairment testing during the fourth quarter of 2023 and concluded that fair value was less than carrying value in its Early Development (ED) reporting unit within the BLS segment. As a result, the Company recorded a goodwill impairment charge in the BLS segment.

F-3

Index

We identified goodwill for the ED reporting unit as a critical audit matter due to the significant estimates and assumptions used by management to estimate the fair value of the reporting unit. Performing audit procedures to evaluate management's estimate of fair value of the reporting unit required a high degree of auditor judgment and an increased extent of effort, including the need to involve our fair value specialists.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the market multiples selected by management for the market-based valuation approach and management’s estimates related to the cash flows arising from future revenues and profitability, terminal growth rates, and the discount rate used in the income-based valuation approach included the following, among others:

•We tested the effectiveness of controls over management's goodwill impairment evaluation, including those over the determination of the fair value of the reporting unit, such as controls related to management's selection of market multiples, cash flows arising from future revenues and profitability, the terminal growth rate, and the discount rate.

•We evaluated the reasonableness of management’s forecasts by comparing the forecasts to (1) historical forecasts and the associated actual results, (2) internal communications to management, and (3) forecasted information included in analyst and industry reports for the Company and certain of its peer companies.

•With the assistance of our fair value specialists, we evaluated the reasonableness of the (1) valuation methodology, (2) the discount rate, and (3) market activity by:

◦Testing the source information underlying the determination of the discount rate and market multiples, including the mathematical accuracy of the calculations.

◦Developing a range of independent estimates and comparing those to the discount rate and market multiples selected by management.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of Laboratory Corporation of America Holdings

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Laboratory Corporation of America Holdings and subsidiaries (the “Company”) as of December 31, 2023, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control – Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2023, of the Company and our report dated February 26, 2024, expressed an unqualified opinion on those financial statements.

Basis for Opinion

The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Report of Management on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Dollars and shares in millions, except per share data)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Financial Statement Presentation

Laboratory Corporation of America® Holdings (Labcorp or the Company) (Labcorp or the Company) is a global leader of innovative and comprehensive laboratory services that provides vital information to help doctors, hospitals, pharmaceutical companies, researchers, and patients make clear and confident decisions. By leveraging its unparalleled diagnostics and drug development capabilities, the Company provides insights and accelerates innovations to improve health and improve lives. With more than 67,000 employees, the Company serves clients in more than 100 countries.

The Company reports its business in two segments, Labcorp Diagnostics (Dx) and Biopharma Laboratory Services (BLS), formerly Drug Development (DD). For further financial information about these segments, including information for each of the last three fiscal years regarding revenue, operating income, and other important information, see Note 20 Business Segment Information. In 2023, Dx and BLS contributed 77% and 23%, respectively, of revenues to the Company, and in 2022 contributed 77% and 23%, respectively.

The consolidated financial statements include the accounts of the Company and its majority-owned subsidiaries for which it exercises control. Long-term investments in affiliated companies in which the Company exercises significant influence, but which it does not control, are accounted for using the equity method. Investments in which the Company does not exercise significant influence (generally, when the Company has an investment of less than 20% and no representation on the investee's board of directors) are accounted for at fair value or at cost minus impairment adjusted for observable price changes in orderly transactions for an identical or similar investment of the same issuer for those investments that do not have readily determinable fair values. All significant inter-Company transactions and accounts have been eliminated. The Company does not have any variable interest entities or special purpose entities whose financial results are not included in the consolidated financial statements.

The financial statements of the Company's operating foreign subsidiaries are measured using the local currency as the functional currency. Assets and liabilities are translated at exchange rates as of the balance sheet date. Revenues and expenses are translated at average monthly exchange rates prevailing during the year. Resulting translation adjustments are included in “Accumulated other comprehensive income.”

On June 30, 2023, the Company completed the separation (spin-off) of Fortrea Holdings Inc. (Fortrea), formerly the Company’s Clinical Development and Commercialization Services (CDCS) business, into a separate, publicly-traded company. All current and historical operating results of Fortrea are presented as Discontinued Operations, net of tax, in the consolidated statement of operations. As a result of the spin-off the Company recast segment results to exclude the historical results of the CDCS business for all periods presented. The remaining operations of the previously reported Drug Development segment has been renamed the Biopharma Laboratory Services segment. Additional disclosures regarding the spin-off of Fortrea are provided in Note 2 (Discontinued Operations).

Reimbursable Out-of-Pocket Expenses

BLS pays on behalf of its customers certain out-of-pocket costs for which the Company is reimbursed at cost, without mark-up or profit. Out-of-pocket costs paid by BLS are reflected in cost of revenues, while the reimbursements received are reflected in revenues in the consolidated statements of operations.

Cost of Revenues

Cost of revenue includes direct labor and related benefit charges, reimbursable expenses, other direct costs, shipping and handling fees, and an allocation of facility charges and information technology costs.

Selling, General and Administrative Expenses

Selling, general and administrative expenses consist primarily of administrative payroll and related benefit charges, advertising and promotional expenses, administrative travel and an allocation of facility charges and information technology costs. Cost of advertising is expensed as incurred.

Research and Development

The Company expenses R&D costs as incurred.

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reported periods. Significant estimates include implicit price concessions, revenue estimates, the allowances for doubtful accounts, deferred tax assets, fair values of acquired assets and assumed liabilities in business combinations, fair value of goodwill and indefinite-lived intangible assets, amortization lives for acquired intangible assets, and accruals for self-insurance reserves, litigation reserves and pensions. Actual results could differ from those estimates.

The extent to which the COVID-19 pandemic has and will continue to impact the Company’s business and financial results depend on numerous evolving factors including, but not limited to the magnitude and duration of the COVID-19 pandemic, the impact to worldwide macroeconomic conditions including interest rates, employment rates and health insurance coverage, the speed of the anticipated recovery, and governmental and business reactions to the pandemic. The Company assessed certain accounting matters that generally require consideration of forecasted financial information in context with the information reasonably available to the Company and the unknown future impacts of COVID-19 as of December 31, 2023, and through the date of this Annual Report. The accounting matters assessed included, but were not limited to, the Company’s implicit price concessions and credit losses, equity investments, and the carrying value of goodwill and other long-lived assets. The Company’s future assessment of the magnitude and duration of the COVID-19 pandemic, as well as other factors, could impact the Company’s consolidated financial statements in future reporting periods.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable.

The Company maintains cash and cash equivalents with various major financial institutions. The total cash and cash equivalent balances that exceeded the balances insured by the Federal Deposit Insurance Commission, were approximately $534.7 and $428.1 at December 31, 2023, and 2022, respectively.

Substantially all of the Company’s accounts receivable are with companies in the healthcare or pharmaceutical industry and individuals. However, concentrations of credit risk are mitigated due to the number of the Company’s customers as well as their dispersion across many different geographic regions.

Although Dx has receivables due from U.S. and state governmental agencies, the Company does not believe that such receivables represent a credit risk since the related healthcare programs are funded by U.S. and state governments, and payment is primarily dependent upon submitting appropriate documentation. Accounts receivable balances (gross) from Medicare and Medicaid were $86.5 and $85.8 at December 31, 2023, and 2022, respectively.

For the Company's operations in Ontario, Canada, the Ontario Ministry of Health and Long-Term Care (Ministry) determines who can establish a licensed community medical laboratory and caps the amount that each of these licensed laboratories can bill the government sponsored healthcare plan. The Ontario government-sponsored healthcare plan covers the cost of commercial laboratory testing performed by the licensed laboratories. The provincial government discounts the annual testing volumes based on certain utilization discounts and establishes an annual maximum it will pay for all community laboratory tests. The agreed-upon reimbursement rates are subject to Ministry review at the end of year and can be adjusted (at the government's discretion) based upon the actual volume and mix of test work performed by the licensed healthcare providers in the province during the year. The capitated accounts receivable balance from the Ontario government sponsored healthcare plan was CAD 5.5 at December 31, 2023. There were no capitated accounts receivables from the Ontario government sponsored healthcare plan at December 31, 2022.

The portion of the Company's accounts receivable due from patients comprises the largest portion of credit risk. At December 31, 2023, and 2022, receivables due from patients represented approximately 20.4% and 15.3% of the Company's consolidated gross accounts receivable, respectively. The Company applies assumptions and judgments including historical collection experience and reasonable and supportable forecasts for assessing collectability and determining allowances for doubtful accounts for accounts receivable from patients.

Earnings per Share

Basic earnings per share is computed by dividing net earnings attributable to Laboratory Corporation of America Holdings by the weighted average number of common shares outstanding. Diluted earnings per share is computed by dividing net earnings including the impact of dilutive adjustments by the weighted average number of common shares outstanding plus potentially dilutive shares, as if they had been issued at the earlier of the date of issuance or the beginning of the period

Stock Compensation Plans

The Company measures stock compensation cost for all equity awards at fair value on the date of grant and recognizes compensation expense over the service period for awards expected to vest. The fair value of restricted stock units is determined based on the number of shares granted and the quoted price of the Company’s Common Stock on the grant date. The grant date fair value of performance awards is based on a Monte Carlo simulated fair value for the relative (as compared to the peer companies) total shareholder return component of the performance awards. Such value is recognized as an expense over the service period, net of estimated forfeitures and the Company's determination of whether it is probable that the performance targets will be achieved. At the end of each reporting period, the Company reassesses the probability of achieving performance targets. The estimation of equity awards that will ultimately vest requires judgment, and the Company considers many factors when estimating expected forfeitures, including types of awards, employee class, and historical experience. Forfeitures are recognized as a reduction of compensation expense in earnings in the period in which they occur.

See Note 14 Stock Compensation Plans for assumptions used in calculating compensation expense for the Company’s stock compensation plans.

Cash Equivalents

Cash and cash equivalents consist of highly liquid instruments, such as commercial paper, time deposits, and other money market instruments, which have maturities when purchased of three months or less.

Supplies Inventory

Inventories, consisting primarily of purchased laboratory and customer supplies and finished goods, are stated at the lower of cost (first-in, first-out) or net realizable value. Supplies accounted for $385.1 and $412.8 and finished goods accounted for $89.5 and $57.8 of total inventory at December 31, 2023, and 2022, respectively. The Company's inventory reserve balance was $66.1 and $23.3, as of December 31, 2023 and 2022, respectively.

Property, Plant and Equipment

Property, plant and equipment are recorded at cost. Depreciation and amortization expense is computed on all classes of assets based on their estimated useful lives, as indicated below, using the straight-line method.


	Years
Buildings and building improvements	10	-	55
Machinery and equipment	3	-	10
Furniture and fixtures	5	-	10
Software	3	-	10

Leasehold improvements are amortized over the shorter of their estimated useful lives or the term of the related leases. Expenditures for repairs and maintenance are charged to operations as incurred. Retirements, sales and other disposals of assets are recorded by removing the cost and accumulated depreciation from the related accounts with any resulting gain or loss reflected in the consolidated statements of operations.

(Dollars and shares in millions, except per share data)

Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. If the carrying value is no longer recoverable based upon the undiscounted future cash flows of the asset, the amount of the impairment is the difference between the carrying amount and the fair value of the asset.

Capitalized Software Costs

The Company capitalizes purchased software that is ready for service and capitalizes software development costs incurred on significant projects starting from the time that the preliminary project stage is completed and the Company commits to funding a project until the project is substantially complete and the software is ready for its intended use. Capitalized costs include direct material and service costs and payroll and payroll-related costs. Research and development (R&D) costs and other computer software maintenance costs related to software development are expensed as incurred. Capitalized software costs are amortized using the straight-line method over the estimated useful life of the underlying system ranging from three to fifteen years, generally five years. Amortization begins once the underlying system is substantially complete and ready for its intended use.

Goodwill and Indefinite-lived Intangibles

The Company assesses goodwill and indefinite-lived intangibles, which are not amortized, for impairment at least annually or whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. The annual impairment test for goodwill includes an option to perform a qualitative assessment of whether it is more likely than not that a reporting unit's fair value is less than its carrying value. Reporting units are businesses with discrete financial information that is available and reviewed by management. If the Company determines that it is more likely than not that the fair value of a reporting unit is less than its carrying value, then the Company performs the quantitative goodwill impairment test. The Company may also choose to bypass the qualitative assessment for any reporting unit in its goodwill assessment and proceed directly to performing the quantitative assessment. The Company recognizes an impairment charge for the amount by which the reporting unit's carrying amount exceeds its fair value.

Management performed its annual goodwill and intangible asset impairment testing as of the beginning of the fourth quarter of 2023. The Company elected to perform the qualitative assessment for goodwill and intangible assets for the domestic Dx reporting unit and the Clinical Trials Testing Solutions (CTTS) reporting unit, and a quantitative assessment for the Early Development (ED) reporting unit, and the Canadian reporting unit which includes indefinite-lived assets consisting of acquired Canadian licenses. Based upon the results of the qualitative and quantitative assessments, the Company concluded that the fair values of its domestic Dx, CTTS and Canadian reporting units, as of October 1, 2023, were greater than the carrying values. However, due to lower demand in the ED reporting unit in late 2023, which the Company anticipates will continue into early 2024 there is an expectation of lower near term revenue and profitability. Therefore, the Company concluded that the fair value of the ED reporting unit was less than carrying value and recorded a goodwill impairment of $333.6 in the BLS segment.

Accordingly, there can be no assurance that the estimates and assumptions made for the purposes of the goodwill impairment analysis will prove to be accurate predictions of future performance. It is possible that the Company's conclusions regarding impairment or recoverability of goodwill or intangible assets in any reporting unit could change in future periods. There can be no assurance that the estimates and assumptions used in the Company's goodwill and intangible asset impairment testing performed as of the beginning of the fourth quarter of 2023 will prove to be accurate predictions of the future, if, for example, (i) the businesses do not perform as projected, (ii) overall economic conditions in 2024 or future years vary from current assumptions (including changes in discount rates), (iii) business conditions or strategies for a specific reporting unit change from current assumptions, including loss of major customers, (iv) investors require higher rates of return on equity investments in the marketplace or (v) enterprise values of comparable publicly traded companies, or actual sales transactions of comparable companies, were to decline, resulting in lower multiples of revenues and EBITDA.

Intangible Assets

Intangible assets with finite lives are amortized on a straight-line basis over the expected periods to be benefited, as set forth in the table below, such as legal life for patents and technology and contractual lives for non-compete agreements.


	Years
Customer relationships	10	-	36
Patents, licenses and technology	3	-	15
Non-compete agreements	3	-	5
Trade names	1	-	15

Intangible assets with finite lives are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. If the carrying value is no longer recoverable based upon the undiscounted future cash flows of the asset, the amount of the impairment is the difference between the carrying amount and the fair value of the asset.

Debt Issuance Costs

The costs related to the issuance of debt are capitalized, netted against the related debt for presentation purposes and amortized to interest expense over the terms of the related debt.

Professional Liability

The Company is self-insured (up to certain limits) for professional liability claims arising in the normal course of business, generally related to the testing and reporting of laboratory test results. The Company estimates a liability that represents the ultimate exposure for aggregate losses below those limits. The liability is based on assumptions and factors for known and incurred but not reported claims, including the frequency and payment trends of historical claims.

Leases

All leases with a lease term greater than 12 months, regardless of lease type classification, are recorded as an obligation on the balance sheet with a corresponding right-of-use asset. Both finance and operating leases are reflected as liabilities on the commencement date of the lease based on the present value of the lease payments to be made over the lease term. Right-of-use assets are valued at the initial measurement of the lease liability, plus any initial direct costs or rent prepayments, minus lease incentives and any deferred lease payments. The classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease.

A certain number of these leases contain rent escalation clauses either fixed or adjusted periodically for inflation or market rates that are factored into the Company's determination of lease payments. The Company also has variable lease payments that do not depend on a rate or index, for items such as volume purchase commitments, which are recorded as variable cost when incurred. As most of the Company's leases do not provide an implicit rate, the Company estimates an incremental borrowing rate based on the credit quality of the Company and by comparing interest rates available in the market for similar borrowings, and adjusting this amount based on the impact of collateral over the term of each lease. The Company uses this rate to discount payments to present value. Some operating leases contain renewal options, some of which also include options to early terminate the leases. The exercise of these options is at the Company's discretion and the Company evaluates each renewal option to determine if it is reasonably possible to be exercised and should be included in the accounting lease term. See Note 5 Leases to the Consolidated Financial Statements.

Income Taxes

The Company accounts for income taxes utilizing the asset and liability method. Under this method deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying

F-15

Index

LABORATORY CORPORATION OF AMERICA HOLDINGS AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Dollars and shares in millions, except per share data)

amounts of existing assets and liabilities and their respective tax bases and for tax loss carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company does not recognize a tax benefit unless the Company concludes that it is more likely than not that the benefit will be sustained on audit by the taxing authority based solely on the technical merits of the associated tax position. If the recognition threshold is met, the Company recognizes a tax benefit measured at the largest amount of the tax benefit that the Company believes is greater than 50% likely to be realized. The Company records interest and penalties in income tax expense.

Derivative Financial Instruments

The Company addresses its exposure to market risks, principally the market risk associated with changes in interest rates and currency exchange rates, through a controlled program of risk management that includes, from time to time, the use of derivative financial instruments. The Company does not hold or issue derivative financial instruments for trading purposes. The Company does not believe that its exposure to market risk is material to the Company’s financial position or results of operations.

Interest rate swap agreements, which have been used by the Company from time to time in the management of interest rate exposure, are accounted for at fair value. These derivative financial instruments are accounted for as fair value hedges that increase or decrease the value of the Senior Notes with the offset being recorded as a component of other long-term assets or liabilities, as applicable. As the specific terms and notional amounts of the derivative financial instruments match those of the fixed-rate debt being hedged, the derivative instruments are assumed to be perfectly effective hedges and accordingly, there is no impact to the Company's consolidated statements of operations. Cash flows from the interest rate swaps are including in operating activities.

Cross currency swap agreements, which have been used by the Company to hedge the foreign currency exposure of its net investment in a foreign subsidiary denominated in non-U.S. currency, are accounted for at fair value. Changes in the fair value of the cross-currency swaps are charged or credited through accumulated other comprehensive income in the Consolidated Balance Sheet until the hedged item is recognized in earnings. The cumulative amount of the fair value hedging adjustments are recognized as currency translation within the Consolidated Statements of Comprehensive Earnings.

Foreign currency forward contracts, which have been used by the Company to hedge foreign currency receivables, are recognized as assets or liabilities at their fair value. These contracts do not qualify for hedge accounting and the changes in fair value are recorded directly to earnings. The contracts are short-term in nature and the fair value of these contracts is based on market prices for comparable contracts. The fair value of these contracts is not significant as of December 31, 2023 and 2022.

Fair Value of Financial Instruments

Fair value measurements for financial assets and liabilities are determined based on the assumptions that a market participant would use in pricing an asset or liability. A three-tiered fair value hierarchy draws distinctions between market participant assumptions based on (i) observable inputs such as quoted prices in active markets (Level 1), (ii) inputs other than quoted prices in active markets that are observable either directly or indirectly (Level 2), and (iii) unobservable inputs that require the Company to use present value and other valuation techniques in the determination of fair value (Level 3).

Foreign Currencies

For subsidiaries outside of the U.S. that operate in a local currency environment, income and expense items are translated to U.S. dollars at the monthly average rates of exchange prevailing during the period, assets and liabilities are translated at period-end exchange rates and equity accounts are translated at historical exchange rates. Translation adjustments are accumulated in a separate component of shareholders’ equity in the consolidated balance sheets and are included in the determination of comprehensive income in the consolidated statements of comprehensive earnings and consolidated statements of changes in shareholders’ equity. Transaction gains and losses are included in the determination of net income in the consolidated statements of operations.

2. DISCONTINUED OPERATIONS

A discontinued operation may include a component or a group of components of the Company's operations. A disposal of a component or a group of components is reported in discontinued operations if the disposal represents a strategic shift that has or will have a major effect on the Company's operations and financial results when the following occurs: (i) a component (or group of components) meets the criteria to be classified as held for sale; (ii) the component or group of components is disposed of by sale; or (iii) the component or group of components is disposed of other than by sale (for example, by abandonment or in a distribution to owners in a spin-off). For any component classified as held for sale or disposed of by sale or other than by sale, qualifying for presentation as a discontinued operation, the Company reports the results of operations of the discontinued operations (including any gain or loss recognized on the disposal or loss recognized on classification as held for sale of a discontinued operation), less applicable income taxes (benefit), as a separate component in the consolidated statement of operations for current and all prior periods presented. The Company also reports assets and liabilities associated with discontinued operations as separate line items on the consolidated balance sheet for prior periods.

The spin-off of Fortrea was achieved through the Company’s pro-rata distribution of 100% of the outstanding shares of Fortrea Common Stock to holders of record of Labcorp Common Stock. Each holder of record of Labcorp Common Stock received one share of Fortrea Common Stock for every share of Labcorp Common Stock held at 5:00 p.m., Burlington, North Carolina, time on June 20, 2023, the record date for the distribution (Distribution Date). The Company received external opinions from tax counsel and a private letter ruling from the U.S. Internal Revenue Service (the “IRS”) regarding the qualification of the spin-off of Fortrea as tax-free to Fortrea, the Company and the shareholders of the Company for U.S. federal income tax purposes.

In June 2023, Fortrea, prior to the spin-off and while a subsidiary of the Company, issued $570.0 of 7.500% senior secured notes due 2030 (the Fortrea Notes). The proceeds from the Fortrea Notes were used to fund cash payments of approximately $1,600.0 to the Company in connection with the spin-off. The Company does not guarantee the Fortrea Notes. Also in June 2023, Fortrea entered into three floating secured overnight financing rate (SOFR) credit facilities totaling $1,520.0. These are comprised of a $450.0 Revolver maturing June 30, 2028; a $500.0 Term Loan A maturing June 30, 2028; and a $570.0 Term Loan B maturing June 30, 2030.

In connection with the spin-off, the Company entered into several agreements with Fortrea on or prior to the Distribution Date that, among other things, provide a framework for the Company’s relationship with Fortrea after the spin-off, including a separation and distribution agreement, a tax matters agreement, an employee matters agreement, and a transition services agreement. These agreements contain the key provisions relating to the spin-off, including provisions relating to the principal intercompany transactions required to effect the spin-off, the conditions to the spin-off and provisions governing the relationship between Fortrea and the Company after the spin-off. The costs to provide these services are included in operating income and the service fees earned are included in other income.

Financial Information of Discontinued Operations

Earnings from Discontinued Operations, Net of Tax in the Consolidated Statements of Operations reflect the after-tax results of Fortrea's business and spin-off-related fees, and do not include any allocation of general corporate overhead expense or interest expense of the Company.

Revenues in the U.S. were $10,177.7 (83.7%), $9,930.3 (83.7%) and $10,981.2 (83.6%) for the years ended December 31, 2023, 2022, and 2021.

The following is a description of the current revenue recognition policies of the Company:

Dx Revenues

Dx is an independent clinical laboratory business. It offers a comprehensive menu of frequently requested and specialty diagnostic tests through an integrated network of primary and specialty laboratories across the U.S. In addition to diagnostic testing along with occupational and wellness testing for employers and forensic DNA analysis, Dx also offered a range of other testing services.

Within the Dx segment, a majority of the revenue transactions initiated when Dx receives a requisition order to perform a diagnostic test. The information provided on the requisition form is used to determine the party that will be billed for the testing performed and the expected reimbursement. Dx recognizes revenue and satisfies its performance obligation for services rendered when the testing process is complete and the associated results are reported. The Dx segment also enters into agreements that have monthly and non-testing based fees which are recognized each month as the services are provided.

Revenues are distributed among four payer portfolios - clients, patients, Medicare and Medicaid and third party. Dx considers negotiated discounts and anticipated adjustments, including historical collection experience for the payer portfolio, when revenues are recorded.

The following are descriptions of the Dx payer portfolios:

Clients

Client payers represent the portion of Dx’s revenue related to physicians, hospitals, health systems, accountable care organizations (ACOs), employers and other entities where payment is received exclusively from the entity ordering the testing service. Generally, client sales are recorded on a fee-for-service basis at Dx’s client list price, less any negotiated discount. A portion of client billing is for laboratory management services, collection kits and other non-testing services or products. In these cases, revenue is recognized when services are rendered or delivered.

Patients

This portfolio includes revenue from uninsured patients and member cost-share for insured patients (e.g., coinsurance, deductibles and non-covered services). Uninsured patients are billed based upon Dx’s patient list fee schedules, net of any discounts negotiated with physicians on behalf of their patients. Dx bills insured patients as directed by their health plan and after consideration of the fees and terms associated with an established health plan contract.

F-19

Index

LABORATORY CORPORATION OF AMERICA HOLDINGS AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Dollars and shares in millions, except per share data)

Medicare and Medicaid

This portfolio relates to fee-for-service revenue from traditional Medicare and Medicaid programs. Revenue from these programs is based on the fee schedule established by the related government authority. In addition to contractual discounts, other adjustments including anticipated payer denials are considered when determining revenue. Any remaining adjustments to revenue are recorded at the time of final collection and settlement. These adjustments are not material to Dx’s results of operations in any period presented.

Third Party

Third party includes revenue related to managed care organizations (MCOs). The majority of Dx's third-party revenue is reimbursed on a fee-for-service basis. These payers are billed at Dx's established list price and revenue is recorded net of contractual discounts. The majority of Dx’s MCO sales are recorded based upon contractually negotiated fee schedules with sales for non-contracted MCOs recorded based on historical reimbursement experience.

In addition to contractual discounts, other adjustments including anticipated payer denials are considered when determining revenue. Any remaining adjustments to revenue are recorded at the time of final collection and settlement. These adjustments are not material to Dx’s results of operations in any period presented.

Third-party reimbursement is also received through capitation agreements with MCOs and independent physician associations. Under capitated agreements, revenue is recognized based on a negotiated per-member, per-month payment for an agreed upon menu of tests, or based upon the proportionate share earned by Dx from a capitation pool. When the agreed upon reimbursement is based solely on an established rate per member, revenue is not impacted by the volume of testing performed. Under a capitation pool arrangement, the aggregate value of an established rate per member is distributed based on the volume and complexity of the procedures performed by laboratories participating in the agreement. Dx recognizes revenue monthly, based upon the established capitation rate or anticipated distribution from a capitated pool.

BLS Revenues

BLS revenue is generally recognized over time, as the services are delivered to the customer, based on the extent of progress towards completion of the performance obligation. The selection of the method to measure progress towards completion requires judgment and is based on the nature of the products or services to be provided. The majority of the segment's contracts contain a single performance obligation, as the segment provides a significant service of integrating all promises in the contract and the promises are highly interdependent and interrelated with one another. For contracts that include multiple performance obligations, BLS allocates the contract value to the goods and services based on a customer price list, if available. If a price list is not available, BLS will estimate the transaction price using either market prices or an “expected cost plus margin” approach. The total contract value is estimated at the beginning of the contract, and is equal to the amount expected to be billed to the customer. These contracts generally take the form of fixed-price or fee-for-service arrangements subject to pricing adjustments based on changes in scope. Fixed-price contracts are typically recognized as revenue over time based on a proportional-performance basis, using either input or output methods that are specific to the service provided. In an output method, revenue is determined by dividing the actual units of output achieved by the total units of output required under the contract and multiplying that percentage by the total contract value. When using an input method, revenue is recognized by dividing the actual costs incurred by the total estimated cost expected to complete the contract, and multiplying that percentage by the total contract value. Contract costs principally include direct labor costs, research model costs and allocated overhead. The estimate of total costs expected to complete the contract requires significant judgment, and these estimates are reviewed periodically. Any adjustments to the estimates are recognized on a cumulative catch-up basis in the period they become known.

Most contracts are terminable with or without cause by the customer, either immediately or upon notice. These contracts often require payment to BLS of expenses, fees earned to date and, in some cases, a termination fee or a payment to BLS of some portion of the fees or profits that could have been earned by BLS under the contract if it had not been terminated early. Termination fees are included in revenues when services have been performed and realization is assured.

Accounts Receivable, Unbilled Services and Unearned Revenue

Differences in the timing of revenue recognition and associated billing and cash collections result in recording accounts receivable, unbilled services and unearned revenue in the consolidated balance sheet. Payments received in advance of services being provided are contract liabilities recognized as unearned revenue. Revenue recognized in advance of billing are recognized as unbilled services and the majority of BLS's unbilled services represent unbilled receivables. Once a customer is invoiced, the contract asset is reduced for the amount billed, and a corresponding accounts receivable is recognized. All contract assets are billable to customers within one year from the respective balance sheet date. The following table provides information about accounts receivable, unbilled services, and unearned revenue from contracts with customers:


	December 31, 2023		December 31, 2022
Dx accounts receivable	$	1,135.2	$	1,046.9
BLS accounts receivable	810.8		769.4
Less BLS allowance for doubtful accounts	(32.7)		(30.8)
Accounts receivable	$	1,913.3	$	1,785.5

Gross unbilled services	$	192.9	$	222.3
Less reserve for unbilled services	(7.5)		(10.6)
Unbilled services	$	185.4	$	211.8

Unearned revenue	$	421.7	$	310.6

Revenue recognized during the period, that was included in the unearned revenue balance at the beginning of the period, for the years ended December 31, 2023, 2022, and 2021 was $78.9, $99.7, and $110.7, respectively.

Share Repurchase Program

On August 8, 2023, the Company entered into accelerated share repurchase agreements (collectively, the ASR Agreements) with two different banks, Goldman Sachs & Co. LLC and Morgan Stanley & Co. LLC (collectively, the Financial Institutions), to repurchase approximately $1,000.0 in the aggregate of the Company’s Common Stock (Common Stock), as part of the Company’s Common Stock repurchase program.

During the fourth quarter of 2021, the board of directors (the Board) adopted a new share repurchase plan authorizing up to $2,500.0 of the Company's shares in addition to the remaining amount outstanding under the previous plan. Under this plan, the Company commenced an Accelerated Share Repurchase (ASR) program. At inception, the Company paid $1,000.0 and received 2.7 shares based on a calculation using 80% of the shares calculated at the price at the inception of the ASR agreements with two different banks, Goldman Sachs & Co. LLC and Barclays Bank PLC. The initial shares received under the ASR program were removed from the outstanding share count in 2021. During the twelve months ended December 31, 2022, 0.9 shares were retired as part of this ASR program.

The table below provides a rollforward of the valuation allowance:

The Company has U.S. federal tax loss carryforwards of approximately $127.0, which expire periodically through 2037, as well as post-2017 carryforwards of $179.1 that are limited to 80% of taxable income and have an indefinite carryforward period. The utilization of tax loss carryforwards is limited due to change of ownership rules; however, at this time, the Company expects to fully utilize substantially all U.S. federal tax loss carryforwards with the exception of approximately $8.4 for which a full valuation allowance has been provided. The Company has U.S. state tax loss carryforwards of $442.8, a portion of which expire annually, and on which a valuation allowance of $403.0 has been provided. In addition to federal and state tax loss carryforwards, the Company has other federal and state attribute carryforwards of $114.4. A portion of these attribute carryforwards will expire through 2024 and have a valuation allowance of $69.2 while the remainder have indefinite carryforward periods. The Company has foreign tax loss carryforwards of $117.2, the majority of which have indefinite carryforward periods, but a valuation allowance of $7.9 has been provided for jurisdictions where the future tax benefits of the attributes are not more likely than not to be realized. Additionally, the Company has foreign tax loss carryforwards of $444.3 which expire periodically through 2038 and foreign tax loss carryforwards of $14.5 which expire periodically through 2043 that have full valuation allowances. In addition to the foreign net operating losses, the Company has a foreign capital loss carryforward of $27.4 with an indefinite carryforward period and a full valuation allowance.

The valuation allowance decreased from $151.3 in 2022 to $150.2 in 2023 primarily due to releases of valuation allowances on certain U.S. capital losses and state net operating losses which were offset by the establishment of valuation allowances on acquired net operating losses recorded through purchase accounting.

Unrecognized income tax benefits were $29.9 and $37.5 at December 31, 2023, and 2022, respectively. It is anticipated that the amount of the unrecognized income tax benefits will decrease by $0.2 within the next 12 months due to statute of limitation lapses; however, these changes are not expected to have a significant impact on the results of operations, cash flows or the financial position of the Company.

The Company recognizes interest and penalties related to unrecognized income tax benefits in income tax expense. Accrued interest and penalties related to uncertain tax positions totaled $0.1 and $2.3 as of December 31, 2023, and 2022, respectively. During the years ended December 31, 2023, 2022 and 2021, the Company recognized $0.0, $0.8 and $0.0, respectively, in interest and penalties expense, which was offset by a benefit from reversing previous accruals for interest and penalties of $1.8, $0.0 and $1.1, respectively.

The following table shows a reconciliation of the unrecognized income tax benefits, excluding interest and penalties, from uncertain tax positions for the years ended December 31, 2023, 2022 and 2021:


	2023		2022		2021
Balance as of January 1	$	37.5	$	39.6	$	18.6
Increase in reserve for tax positions taken in the current year	1.8		1.8		—

Decrease in reserve as a result of lapses in the statute of limitations	(8.6)		(4.1)		(2.0)
Balance as of December 31	$	29.9	$	37.5	$	39.6

Also included in the balance of unrecognized tax benefits as of December 31, 2023, 2022 and 2021, are $0.0, $0.0 and $0.9, respectively, of tax benefits that, if recognized, would result in adjustments to other tax accounts, primarily deferred taxes. As of December 31, 2023, 2022 and 2021 there are $29.9, $37.5 and $38.7, respectively, of tax benefits that, if recognized, would favorably impact the effective income tax rate.

The Company has substantially concluded all U.S. federal income tax matters for years through 2018 and is currently under IRS examination for tax years 2019 and 2020. Substantially all material state and local and foreign income tax matters have been concluded through 2017 and 2018, respectively. The Company has various state and foreign income tax examinations ongoing throughout the year. The Company believes adequate provisions have been recorded related to all open tax years.

As a result of the Tax Cuts and Jobs Act (TCJA), the Company was effectively taxed on all of its previously unremitted foreign earnings. The TCJA also enacts a territorial tax system that allows, for the most part, tax-free repatriation of foreign earnings. The Company still considers the earnings of its foreign subsidiaries to be permanently reinvested, but, if repatriation were to occur, the Company would be required to accrue U.S. taxes, if any, and remit applicable withholding taxes as appropriate. The Company has unremitted earnings and profits of $607.6 and $927.4 that are permanently reinvested in its foreign subsidiaries as of December 31, 2023, and 2022, respectively. A determination of the amount of the unrecognized deferred tax liability related to these undistributed earnings is not practicable due to the complexity and variety of assumptions necessary based on the manner in which the undistributed earnings would be repatriated.

Pillar Two legislation arising from the Organisation for Economic Co-operation and Development’s base erosion and profit shifting initiative has been enacted or substantively enacted in certain jurisdictions the Company operates. The legislation will be effective for the Company’s financial year beginning January 1, 2024. The Company is in scope of the enacted or substantively enacted legislation and has performed an assessment of the Company’s potential exposure to Pillar Two income taxes.

The assessment of the potential exposure to Pillar Two income taxes is based on the most recent tax filings, country-by-country reporting, and financial statements for the constituent entities in the Company. Based on the assessment, the Pillar Two effective tax rates in most of the jurisdictions in which the Company operates are above 15%. However, there are a limited number of jurisdictions where the transitional safe harbor relief does not apply and the Pillar Two effective tax rate is close to 15%. The Company does not expect a material exposure to Pillar Two income taxes in those jurisdictions.

14. STOCK COMPENSATION PLANS

Stock Incentive Plans

In 2016, the shareholders approved the Laboratory Corporation of America Holdings 2016 Omnibus Incentive Plan (the Plan). Under the Plan, as of December 31, 2023, there are 9.4 shares authorized for issuance and 3.5 shares available for grant.

Stock Options

The following table summarizes grants of non-qualified options made by the Company to officers, key employees, and non-employee directors under all plans. Stock options are generally granted at an exercise price equal to or greater than the fair market price per share on the date of grant. Also, for each grant, options vest ratably over a period of three years on the anniversaries of the grant date, and have a contractual exercise period of 10 years subject to their earlier expiration or termination.

Changes in options outstanding under the plans for the period indicated were as follows:


	Number of Options	Weighted-Average Exercise Price per Option	Weighted-Average Remaining Contractual Term	Aggregate Intrinsic Value
Outstanding at December 31, 2022	0.5	169.31
Granted	0.1	219.83


Outstanding at December 31, 2023	0.6	174.45	6.0	$	32.2

Exercisable at December 31, 2023	0.5	159.05	5.4	$	31.3

The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (the difference between the Company’s closing stock price on the last trading day of 2023 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on December 31, 2023.

Cash received by the Company from option exercises, the actual tax benefit realized for the tax deductions and the aggregate intrinsic value of options exercised from option exercises under all share-based payment arrangements during the years ended December 31, 2023, 2022, and 2021 were as follows:


	2023		2022		2021
Cash received by the Company	$	2.9	$	7.1	$	6.8
Tax benefits realized	$	0.7	$	1.8	$	1.7

The following table shows the weighted average grant-date fair values of options issued during the respective year and the weighted average assumptions that the Company used to develop the fair value estimates:



	2023			2022			2021
Fair value per option	$	72.27		$	68.35		$	55.75

Weighted average expected life (in years)	6.0			6.0			6.0

Expected volatility	29.8		%	28.6		%	28.6		%
Expected dividend yield	1.4		%	0.9		%	N/A

The Black Scholes model incorporates assumptions to value stock-based awards. The risk-free interest rate for periods within the contractual life of the option is based on a zero-coupon U.S. government instrument over the contractual term of the equity instrument. Expected volatility of the Company’s stock is based on historical volatility of the Company’s stock. The Company estimates expected option terms through an analysis of actual, historical post-vesting exercise, cancellation and expiration behavior by employees and projected post-vesting activity of outstanding options. Groups of employees and non-employee directors that have similar exercise behavior with regard to option exercise timing and forfeiture rates are considered separately for valuation purposes. For 2023, 2022 and 2021, expense related to the Company’s stock option plan totaled $3.8, $4.3 and $3.6, respectively, and is included in selling, general and administrative expenses.

Restricted Stock, Restricted Stock Units and Performance Shares

The Company grants restricted stock, restricted stock units, and performance shares (non-vested shares) to officers and key employees and grants restricted stock and restricted stock units to non-employee directors. Restricted stock and units typically vest annually in equal one-third increments beginning on the first anniversary of the grant. A performance share grant in 2021 represents a three-year award opportunity for the period 2021-2023, and if earned, vests fully (to the extent earned) in the first quarter of 2024. A performance share grant in 2022 represents a three-year award opportunity for the period of 2022-2024 and, if earned, vests fully (to the extent earned) in the first quarter of 2025. A performance share grant in 2023 represents a three-year award opportunity for the period of 2023-2025 and, if earned, vests fully (to the extent earned) in the first quarter of 2026. Performance share awards are subject to certain earnings per share, revenue, and total shareholder return targets, the achievement of which may increase or decrease the number of shares which the grantee earns and therefore receives upon vesting. Unearned restricted stock and performance share compensation is amortized to expense, when probable, over the applicable vesting periods. For 2023, 2022, and 2021, total restricted stock, restricted stock unit, and performance share compensation expense was $111.1, $97.7 and $114.6, respectively.

The following table shows a summary of non-vested shares for the year ended December 31, 2023:


	Number of Shares	Weighted-Average Grant Date Fair Value
Non-vested at January 1, 2023	1.1	$	231.30
Granted	0.5	224.11
Vested	(0.5)	208.71
Canceled	(0.1)	235.27
Non-vested at December 31, 2023	1.0	$	248.41

Unrecognized Compensation Cost

As of December 31, 2023, there was $83.0 of total unrecognized compensation cost related to non-vested stock options, restricted stock, restricted stock unit and performance share-based compensation arrangements granted under the Company's stock incentive plans. That cost is expected to be recognized over a weighted average period of 1.9 years and will be included in cost of revenues and selling, general and administrative expenses.

Employee Stock Purchase Plan

Under the 2016 Employee Stock Purchase Plan, the Company is authorized to issue 1.8 shares of Common Stock. The plan permits substantially all U.S., Canada and United Kingdom employees to purchase a limited number of shares of Company stock at 85% of market value. The Company issues shares to participating employees semi-annually in January and July of each year, although due to the spin-off of Fortrea shares for the first offering period were issued in May of 2023. Approximately 0.3, 0.2 and 0.2 shares were purchased by eligible employees in 2023, 2022 and 2021, respectively. For 2023, 2022 and 2021, expense related to the Company’s employee stock purchase plan was $13.8, $14.8 and $14.6, respectively.

15. COMMITMENTS AND CONTINGENCIES

The Company is involved from time to time in various claims and legal actions, including arbitrations, class actions, and other litigation (including those described in more detail below), arising in the ordinary course of business. Some of these actions involve claims that are substantial in amount. These matters include, but are not limited to, intellectual property disputes, commercial and contract disputes, professional liability claims, employee-related matters, transaction-related disputes, securities and corporate law matters, and inquiries, including subpoenas and other civil investigative demands, from governmental agencies, Medicare or Medicaid payers and MCOs reviewing billing practices or requesting comment on allegations of billing irregularities that are brought to their attention through billing audits or third parties. The Company receives civil investigative demands or other inquiries from various governmental bodies in the ordinary course of its business. Such inquiries can relate to the Company or other parties, including physicians and other health care providers. The Company works cooperatively to respond to appropriate requests for information.

The Company believes that it is in compliance in all material respects with all statutes, regulations, and other requirements applicable to its commercial laboratory operations and biopharma laboratory services. These industries are, however, subject to extensive regulation, and the courts have not interpreted many of the applicable statutes and regulations. Therefore, the applicable statutes and regulations could be interpreted or applied by a prosecutorial, regulatory, or judicial authority in a manner that would adversely affect the Company. Potential sanctions for violation of these statutes and regulations include significant civil and criminal penalties, fines, the loss of various licenses, certificates and authorizations, additional liabilities from third-party claims, and/or exclusion from participation in government programs.

Many of the current claims and legal actions against the Company are in preliminary stages, and many of these cases seek an indeterminate amount of damages. The Company records an aggregate legal reserve, which is determined using calculations based on historical loss rates and assessment of trends experienced in settlements and defense costs. In accordance with FASB Accounting Standards Codification Topic 450 “Contingencies,” the Company establishes reserves for judicial, regulatory, and arbitration matters outside the aggregate legal reserve if and when those matters present loss contingencies that are both probable and reasonably estimable and would exceed the aggregate legal reserve. When loss contingencies are not both probable and reasonably estimable, the Company does not establish separate reserves.

The Company is unable to estimate a range of reasonably probable loss for the proceedings described in more detail below in which damages either have not been specified or, in the Company's judgment, are unsupported and/or exaggerated and (i) the proceedings are in early stages, (ii) there is uncertainty as to the outcome of pending appeals or motions, (iii) there are significant factual issues to be resolved, and/or (iv) there are novel legal issues to be presented. For these proceedings, however, the Company does not believe, based on currently available information, that the adverse outcomes are probable and reasonably estimable, and it does not believe they will have a material adverse effect on the Company's financial statements.

The Company has received various subpoenas and other civil investigative demands related to Medicaid billing. In October 2009, the Company received a subpoena from the State of Michigan Department of Attorney General seeking documents related to its billing to Michigan Medicaid. The Company cooperated with this request. In October 2013, the Company received a Civil Investigative Demand from the State of Texas Office of the Attorney General requesting documents related to its billing to Texas Medicaid. The Company cooperated with this request. On October 5, 2018, the Company received a second Civil Investigative Demand from the State of Texas Office of the Attorney General requesting documents related to its billing to Texas Medicaid. The Company cooperated with this request. On January 26, 2021, the Company was notified that a qui tam

Petition was pending under seal in the District Court, 250th Judicial District, Travis County, Texas, and that the State of Texas has intervened. On April 14, 2021, the Petition was unsealed. The Petition alleges that the Company submitted claims for reimbursement to Texas Medicaid that were higher than permitted under Texas Medicaid’s alleged “best price” regulations, and that the Company offered remuneration to Texas health care providers in the form of discounted pricing for certain laboratory testing services in exchange for the providers’ referral of Texas Medicaid business to the Company. The Petition seeks actual and double damages and civil penalties, as well as recovery of costs, attorney's fees, and legal expenses. On August 1, 2022, the District Court entered an order granting the Company's Motion for Partial Summary Judgment with respect to the claim that the Company submitted claims for reimbursement to Texas Medicaid that were higher than permitted under Texas Medicaid's alleged “best price” regulations. Plaintiffs filed a Notice of Non-Suit and Motion for Entry of Final Judgment and, on November 11, 2022, the court entered a Judgment. Plaintiffs filed a Notice of Appeal with respect to the court's order granting the Company's Motion for Partial Summary Judgment, referenced above. The Company will vigorously defend the lawsuit.

On August 31, 2015, the Company was served with a putative class action lawsuit, Patty Davis v. Laboratory Corporation of America, et al., filed in the Circuit Court of the Thirteenth Judicial Circuit for Hillsborough County, Florida. The complaint alleges that the Company violated the Florida Consumer Collection Practices Act by billing patients who were collecting benefits under the Workers' Compensation Statutes. The lawsuit seeks injunctive relief and actual and statutory damages, as well as recovery of attorney's fees and legal expenses. In April 2017, the Circuit Court granted the Company’s Motion for Judgment on the Pleadings. The Plaintiff appealed the Circuit Court’s ruling to the Florida Second District Court of Appeal. On October 16, 2019, the Florida Second District Court of Appeal reversed the Circuit Court’s dismissal, but certified a controlling issue of Florida law to the Florida Supreme Court. On February 17, 2020, the Florida Supreme Court accepted jurisdiction of the lawsuit. The court held oral arguments on December 9, 2020. On May 26, 2022, the Florida Supreme Court issued an opinion approving the result of the Florida Second District Court of Appeal in favor of the Plaintiff. The Company will vigorously defend the lawsuit.

On December 29, 2021, the Company was served with a putative class action lawsuit, Nathaniel J. Nolan, et al. v. Laboratory Corporation of America Holdings, filed in the U.S. District Court for the Middle District of North Carolina. The complaint alleges that the Company's patient acknowledgement of estimated financial responsibility form is misleading. The lawsuit seeks a declaratory judgment under the consumer protection laws of Nevada and Florida that the form is materially misleading and deceptive, an injunction barring the use of the form, damages on behalf of an alleged class, and attorney's fees and expenses. On February 28, 2022, the Company filed a Motion to Dismiss all claims. On February 13, 2023, the court entered an order granting the Company's Motion to Dismiss. On March 13, 2023, Plaintiffs filed a Notice of Appeal. The Company will vigorously defend the Nolan lawsuit.

On April 1, 2019, Covance Research Products was served with a Grand Jury Subpoena issued by the Department of Justice (DOJ) in Miami, Florida requiring the production of documents related to the importation into the United States of live non-human primate shipments originating from or transiting through China, Cambodia, and/or Vietnam from April 1, 2014 through March 28, 2019. The Company is cooperating with the DOJ.

On May 14, 2019, Retrieval-Masters Creditors Bureau, Inc. d/b/a American Medical Collection Agency (AMCA), an external collection agency, notified the Company about a security incident AMCA experienced that may have involved certain personal information about some of the Company’s patients (the AMCA Incident). The Company referred patient balances to AMCA only when direct collection efforts were unsuccessful. The Company’s systems were not impacted by the AMCA Incident. Upon learning of the AMCA Incident, the Company promptly stopped sending new collection requests to AMCA and stopped AMCA from continuing to work on any pending collection requests from the Company. AMCA informed the Company that it appeared that an unauthorized user had access to AMCA’s system between August 1, 2018, and March 30, 2019, and that AMCA could not rule out the possibility that personal information on AMCA’s system was at risk during that time period. Information on AMCA’s affected system from the Company may have included name, address, and balance information for the patient and person responsible for payment, along with the patient’s phone number, date of birth, referring physician, and date of service. The Company was later informed by AMCA that health insurance information may have been included for some individuals, and because some insurance carriers utilize the Social Security Number as a subscriber identification number, the Social Security Number for some individuals may also have been affected. No ordered tests, laboratory test results, or diagnostic information from the Company were in the AMCA affected system. The Company notified individuals for whom it had a valid mailing address. For the individuals whose Social Security Number was affected, the notice included an offer to enroll in credit monitoring and identity protection services that was provided free of charge for 24 months.

Twenty-three putative class action lawsuits were filed against the Company related to the AMCA Incident in various U.S. District Courts. Numerous similar lawsuits have been filed against other health care providers who used AMCA. These lawsuits were consolidated into a multidistrict litigation in the District of New Jersey. On November 15, 2019, the Plaintiffs filed a

Change in Funded Status and Reconciliation of Amounts Recorded in the Balance Sheet

The change in the funded status of the plan and a reconciliation of such funded status to the amounts reported in the consolidated balance sheet as of December 31, 2023, and December 31, 2022, is as follows:


	U.S. Plans				Non-U.S. Plans

Assumptions

Weighted average assumptions used to determine net periodic benefit costs are as follows:


	U. S. Plans						Non-U.S. Plans
	Year ended December 31,
	2023		2022		2021		2023		2022		2021
Discount rate	5.5	%	2.8	%	2.4	%	4.0	%	2.1	%	1.1	%
Salary increases	N/A		N/A		N/A		2.0	%	2.0	%	2.0	%
Expected long term rate of return	6.0	%	4.5	%	6.0	%	5.3	%	3.6	%	3.1	%
Cash balance interest credit rate	4.0	%	4.0	%	4.0	%	N/A		N/A		N/A

A one percentage point decrease or increase in the discount rate would have resulted in a respective increase or decrease in 2023 retirement plan expense of $0.4 for the U.S. Plans. A one percentage point decrease or increase in the discount rate would have resulted in a respective increase or decrease in 2023 retirement plan expense of $0.7 for the Non-U.S. Plans.

Weighted average assumptions used to determine net periodic benefit obligations are as follows:


	U. S. Plans				Non-U.S. Plans
	Year ended December 31,
	2023		2022		2023		2022
Discount rate	5.1	%	5.5	%	4.3	%	4.8	%
Salary increases	N/A		N/A		2.0	%	2.0	%

The discount rate is determined using the weighted-average yields on high-quality fixed income securities that have maturities consistent with the timing of benefit payments. Lower discount rates increase the size of the benefit obligation and generally increase pension expense in the following year; higher discount rates reduce the size of the benefit obligation and generally reduce subsequent-year pension expense.

The expected return on plan assets is the estimated long-term rate of return that will be earned on the investments used to fund the pension obligations. To determine this rate, the Company considers the composition of plan investments, historical returns earned, and expectations about the future. Actual asset over/under performance compared to expected returns will respectively decrease/increase unrecognized loss. The change in the unrecognized loss will change amortization cost in upcoming periods. A one percentage point increase or decrease in the expected return on plan assets would have resulted in a corresponding change in 2023 pension expense of $2.2 for the U.S. Plans. A one percentage point increase or decrease in the expected return on plan assets would have resulted in a corresponding change in 2023 pension expense of $3.1 for the Non-U.S. Plans.

The salary increase assumptions are used to estimate the annual rate at which pay of plan participants will grow. If the rate of growth assumed increases, the size of the pension obligations will increase, as will the amount recorded in Accumulated other comprehensive income (loss) in the Company's Consolidated Statement of Financial Position and amortized into earnings in subsequent periods.

The Company evaluates other assumptions periodically, such as retirement age, mortality and turnover, and updates them as necessary to reflect the Company's actual experience and expectations for the future. Differences between actual results and assumptions utilized are recorded in Accumulated other comprehensive income each period. These differences are amortized into earnings over the remaining average future service of active participating employees or the expected life of inactive participants, as applicable.

primary strategic investment objectives are balancing investment risk and return and monitoring the plan’s liquidity position in order to meet the near-term benefit payment and other cash needs. Target allocation percentages are established at an asset class level by plan fiduciaries. Target allocation ranges are guidelines, not limitations, and occasionally plan fiduciaries will approve allocations above or below a target range.

The weighted average asset allocation of the plan assets as of December 31, 2023, by asset category is as follows:

Pension Funding and Cash Flows

The Company expects to make approximately $16.8 in required contributions to its defined benefit pension plans during 2024. The Company targets funding the minimum required contributions but may make additional contributions into the pension plans in 2024, depending upon factors such as how the funded status of those plans change or to reduce the administrative costs of the plan.

The estimated benefit payments, which were used in the calculation of projected benefit obligations, are expected to be paid as follows:


	U. S. Plans		Non-U. S. Plans
2024	$	21.8	$	16.4
2025	22.4		16.2

Post-employment Retiree Health and Welfare Plan

The Company sponsors a post-employment retiree health and welfare plan for the benefit of eligible employees at certain U.S. subsidiaries who retire after satisfying service and age requirements. This plan is funded on a pay-as-you-go basis and the cost of providing these benefits is shared with the retirees.

Post-retirement Medical Plan

The Company assumed obligations under a subsidiary's post-retirement medical plan. Coverage under this plan is restricted to a limited number of existing employees of the subsidiary. This plan is unfunded and the Company’s policy is to fund benefits as claims are incurred. The effect on operations of the post-retirement medical plan is shown in the following table:

The weighted-average discount rates used in the calculation of the accumulated post-retirement benefit obligation were 5.1% and 5.5% as of December 31, 2023, and 2022, respectively. The healthcare cost trend rate was removed due to the expectation of future funding to be at the same level as the previous year's funding.

The following assumed benefit payments under the Company's post-retirement benefit plan, which reflect expected future service, as appropriate, and which were used in the calculation of projected benefit obligations, are expected to be paid as follows:


2024	$	0.6

Deferred Compensation Plan

The Company has Deferred Compensation Plans (DCP) under which certain of its executives may elect to defer up to 100.0% of their annual cash incentive pay and/or up to 50.0% of their annual base salary and/or eligible commissions subject to annual limits established by the U.S. government. The DCP provides executives a tax efficient strategy for retirement savings and capital accumulation without significant cost to the Company. The Company makes no contributions to the DCP. Amounts deferred by a participant are credited to a bookkeeping account maintained on behalf of each participant, which is used for measurement and determination of amounts to be paid to a participant, or his or her designated beneficiary, pursuant to the terms of the DCP. The amounts accrued under these plans were $107.4 and $96.9 at December 31, 2023, and 2022, respectively. Deferred amounts are the Company's general unsecured obligations and are subject to claims by the Company's creditors. The Company's general assets may be used to fund obligations and pay DCP benefits.

The Company has a noncontrolling interest put related to its Ontario subsidiary that has been classified as mezzanine equity in the Company’s consolidated balance sheets. The noncontrolling interest put is valued at its contractually determined value, which approximates fair value. During the year ended December 31, 2023, the carrying value of the noncontrolling interest put decreased by $1.0 for foreign currency translation.

The Company offers certain employees the opportunity to participate in a DCP. A participant's deferrals are allocated by the participant to one or more of multiple measurement funds, which are indexed to externally managed funds. From time to time, to offset the cost of the growth in the participant's investment accounts, the Company purchases life insurance policies, with the Company named as beneficiary of the policies. Changes in the cash surrender value of the life insurance policies are based upon earnings and changes in the value of the underlying investments, which are typically invested in a similar manner to the participants' allocations. Changes in the fair value of the DCP obligation are derived using quoted prices in active markets based on the market price per unit multiplied by the number of units. The cash surrender value and the DCP obligations are classified within Level 2 because their inputs are derived principally from observable market data by correlation to the hypothetical investments.

Contingent accrued earn-out business acquisition consideration liabilities for which fair values are measured as Level 3 instruments. These contingent consideration liabilities were recorded at fair value on the acquisition date and are remeasured quarterly based on the then assessed fair value and adjusted if necessary. The increases or decreases in the fair value of contingent consideration payable can result from changes in anticipated revenue levels and changes in assumed discount

periods and rates. As the fair value measure is based on significant inputs that are not observable in the market, they are categorized as Level 3.

The carrying amounts of cash and cash equivalents, accounts receivable, income taxes receivable, and accounts payable are considered to be representative of their respective fair values due to their short-term nature. The fair market value of the Senior Notes, based on market pricing, was approximately $4,850.4 and $4,973.9 as of December 31, 2023, and 2022, respectively. The Company's note and debt instruments are considered Level 2 instruments, as the fair market values of these instruments are determined using other observable inputs.

18. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

Interest Rate Swap

During the second quarter of 2021, the Company entered into fixed-to-variable interest rate swap agreements for its 2.70% senior notes due 2031 with an aggregate notional amount of $500.0 and variable interest rates based on three-month SOFR (changed from LIBOR to SOFR during 2023) plus 1.0706%. These agreements were designated as hedges against changes in the fair value of a portion of the Company's long-term debt.

Cross Currency Swaps

During the fourth quarter of 2018, the Company entered into U.S. Dollar (USD) to Swiss Franc cross-currency swap agreements with an aggregate notional value of $600.0. During the second quarter of 2022, the Company terminated $300.0 of those cross-currency swap agreements and entered into new USD to Swiss Franc cross-currency swap agreements with an aggregate notional value of $300.0. The initial cross-currency swap matures in 2025 and the cross currency swap entered into in 2022 matures in 2024. These instruments are designated as a hedge against the impact of foreign exchange movements on its net investment in a Swiss subsidiary.

The table below presents the fair value of derivatives on a gross basis and the balance sheet classification of those instruments:


		December 31, 2023			December 31, 2022
		Fair Value of Derivative			Fair Value of Derivative
	Balance Sheet Caption	Asset	Liability	U.S. Dollar Notional	Asset	Liability	U.S. Dollar Notional
Interest rate swap	Other liabilities	—	69.6	500.0	—	79.7	500.0
Cross currency swaps	Accrued expenses and other/Other liabilities	—	109.0	600.0	—	45.7	600.0

The table below provides information regarding the location and amount of pretax (gains) losses of derivatives designated in fair value hedging relationships:

20. BUSINESS SEGMENT INFORMATION

The following table is a summary of segment information for the years ended December 31, 2023, 2022, and 2021. The “management approach” has been used to present the following segment information. This approach is based upon the way the management of the Company organizes segments within an enterprise for making operating decisions and assessing performance. Financial information is reported on the basis that it is used internally by the chief operating decision maker (CODM) for evaluating segment performance and deciding how to allocate resources to segments. The Company’s chief executive officer has been identified as the CODM.

As a result of the spin-off, the Company recast the segment results to exclude the historical results of Fortrea. Additionally, the remaining operations of the Drug Development segment has been renamed as the BLS segment. Prior periods have been conformed for comparability.

The Company's segment performance measure was changed to exclude the amortization of intangibles and other assets, restructuring and other charges, goodwill and other asset impairments, and certain corporate charges for items such as transaction costs, COVID-19 costs, and other special items. These changes align with how the CODM now evaluates segment performance and allocates resources. Segment asset information is not presented because it is not used by the CODM at the segment level.
